And this is how it looked on 11.07.1942:

I guess those barely visible inscriptions made with bold letters were made by the Finns during the war:

It looks that top of the tower was also modified, if we compare what we see now with the picture taken on 11.07.1942. First, now the opening is round while that time it was hexagonal. Second, there are 4 rectangular slots now near the rim while there were more such slots in 1942:

Батарея Раутаверяйя, дальномерная башня, 11.07.42.jpg

View from the top 28.05.1942:

Similar view nowadays:

Walking Kelisaari further to the West, we see how the trench starts with... a basin to collect rain water?..

The trench gets deeper...

DSCN7435 (3).JPG

...and ends up with really huge pit, which was, as we know now from the document published by Mangrove, an unfinished gunpit for 6 in. Canet gun. The construction began in February 1944, but was never completed.

DSCN7435 (5) Неизвестная яма, 61.336, 31.00267.JPG

There are 2 piles of sledged stones on sides of the pit, and inside one of them this steel device was noticed:

DSCN7435 (8).JPG
DSCN7435 (9).JPG

I guess this device was used for fixing a kind of wooden beams, which beams were used as supports for any kind of lifting device.

The pit is really huge and partly overgrown with young trees, so it's not possible to picture it in whole:

The pit is really interesting - it has additional Г-shaped deepening, in which 2 concrete structures were built:

DSCN7435 (11).JPG
DSCN7435 (12).JPG
DSCN7435 (13).JPG
DSCN7435 (14).JPG

The structures are hollow, they resemble emergency exits or ventilation shafts, but they are built right on the rock basement with no any spar-ladder. There are just small (ca. 30 x 20 cm) openings in walls on top of one structure and in the bottom of another one. No idea what those structures could serve for.

Another remarkable thing is the tunnel excavated in the rock at the end of that "additional deepening", in which 2 concrete structures were built:

The view from the gunpit:

DSCN7435 (15).JPG
DSCN7435 (16).JPG

The view from the opposite side/lakeside:

DSCN7435 (18).JPG
DSCN7435 (19).JPG

There was a hollow made in rock at the lakeside of the tunnel:

DSCN7435 (17).JPG

The only idea I have about the tunnel is that it was unfinished crew shelter or ammo depot. The reason of having entrance also from lakeside is unclear - the water level is ca. 10 m below ground level with visible underwater rocks, so this place might hardly be used as a pier for bringing construction materials by lake. You may easily enter the tunnel from lakeside, but you have to nearly crawl to get out to the gunpit as the entrance on the other side is really small and obviously unfinished.

1) 1:5000 map showing positions of 130. Patteri / 12. Rannikkoprikaati (formerly part of Linnoituspataljoona 12) at Pisi on 15 December 1941. The shape of the river is a bit off but there are 2 x 47-40-OL (QF 3-pounder Hotchkiss by Obukhov) at Pisinranta, 4 x 120 K/78 (Canon de 120 mm long modèle 1878) at Korsukangas between the river and the road and anti-tank guns south of the river near Lake Ladoga. Two of the 120 K/78 positions are listed as "above ground" (maanpäällinen) and two as "excavated" (kaivettu). There is also an artillery observation point near the bridge. The numbers refer to individual 8 men barracks / dugouts.

The pit you found at 60.81882, 32.82986 appears to have been originally a position for a 120 K/78. It would be plausible to think that 3. Moottoroitu Raskas Patteri (3.Mt.Rask.Ptri with 4/122 K/31) used these positions when it was transferred to Pisinjoki on 21 February 1942 and also by I Jaos / 3. Moottoroitu Raskas Patteri (I/3.Mt.Rask.Ptri) when it was transferred to the area on 15 January 1943.
I found the second "excavated" gunpit at 60.82167, 32.82866, but it was either originally more “simple”, than the first one, or just much worse preserved. The logs have rotted completely, the ramp and the cellar are almost indistinguishable.

View from the rear. In the foreground is a ramp, on the left is a ammo cellar, in the background is the front wall of the gunpit:

DSCN9191.JPG

Frontal view:

DSCN9187 Орудийный дворик, 60.82167, 32.82866.JPG

The most interesting thing is that those 2 gunpits have different bearings - 200 degrees south for the first one and 130 degrees south-east for the second one. Of course, the guns could be turned left or right to a certain extent, but it looks that initially they were targeted to different areas - the first one (south) was intended to hit the road running south along Ahvenjärvi while the second one (north) - the road running from south-east, from Pisi.

There are several archive photos of Mustanenänniemi battery at SA-kuva, but all of them related to initial 2 x 57 mm battery set up in February 1942. It looks that battery was located not on the place, where new gunpits with concrete pedestals were later made. So in fact new battery complemented, not replaced the initial one. If we look to the photos of old battery, we'll see that, first, the lakeshore is much lower and sloping there, than ca. 15 - 20 m high steep cliff, on which the new battery was established. Second, there is an island not far from the shore and ca. 90 degrees left from guns' direction.

I think that island is Barmotun (on some maps it is named Barmadan or likewise)...

...Hopefully I will have a chance to check the location of 2 x 57 mm battery, when I get to Valamo next time.
And I really did - here is a right flank gun position at 61.40548, 31.0348:

The bastards who pulled out the gun basement plate, left us only 3 studs and a piece of cable, which they apparently used to pull out the plate:

Only a pile of stones left of the left flank gun position at 61.40559, 31.03516:

This could be a cellar in between and slightly behind gun positions:

Just some more pictures for you to see the size of that pit:

What I didn’t notice last time is that there are 2 mounds of stones going running from the pit in different directions - here is one of them:

In addition to new fire control tower, new observation post was also built. However, I did not find it on present battery - probably it was later turned into something else:

No, that observation post has been preserved - I had just to climb on top of fire control tower of Niikkana battery, what I forgot to do previous time:

The only fact I knew about Verkkosaari was there were 2 x 75 mm guns positioned there in 1942 - 44. Here is a short report after visiting the island.

Full size pictures are available here: https://disk.yandex.ru/d/B7upHa9BzBJ_Fw, I will post just some small previews hereunder.

I hoped to find gunpits or gun basements at best, but found something really unusual - shelters for withdrawable guns on wheels! Such shelters for anti-tank guns are quite usual on both VT Line and Salpalinja, but I never heard about coastal guns of such kind. Here is the first shelter at 61.17598, 30.43915. Note a gunpit on the foreground:

Memorial plaque says: "To sailors of Ladoga naval flotilla, who perished in 1941 - 1944".

As far as I understood, there was an electric cable running from Heinäsenmaa to Verkkosaari and further to the other shore of the island, so here is a cable vault:

Note that the second shelter is a bit different compared to the first one. Were the guns different too?

DSCN9120.JPG

There is a trench with firing positions cut in rock close to the eastern tip. Here it looks like a part of trench was filled back with stones for unknown reason:

DSCN9142.JPG

Unknown object at 61.17541, 30.43993. Looks like a gunpit made of sledged stones, but the walls are too high and diameter is too small for placing any gun there. As follows from nails I found on the bottom with my pinpointer, there was a wooden floor there. Anti-aircraft MG position?
