German shelters in Pskov region, Russia - a Regelbau type?

[JKernwerk]

Eugenius,
If the bunker is for a tankturret (hard for me to make up it is with all the grass and moss) the brickpit next to it is probably for the spend shells.
The pit serves as a bin for the shells that were fired, the cartridges were trown away in the brick recess to prevent the gunners to fall over empty cartridges.
This was usually done for the turrets with heavier guns

JKernwerk, it really could be as you described, but tank turrets were scrapped right after this territory was taken by the Soviet army, bunkers were blown up using captured munition, so the only thing we have is that album with pictures and drawings made in 1944 and a couple of earth pits. There was the third tank turret position, but is was completely destroyed by lumberjacks several years ago.

OK, let's try to continue with German fortifications in Pskov region. In the town of Ostrov the Wehrmacht left this strange building (57.34518, 28.3457):

Actually there are 2 bunkers located end by end with just 1,5 m distance between them. Here is a pass between bunkers:

Larger bunker has just one entrance from the end:

The smaller one has 2 entrances into separate chambers and 2 "windows":

[Eugenius]

Chambers are quite small and filled with garbage:

Larger bunker has 4... ventilation shafts? Windows?

In the other end of larger bunker there was a kind of garage or loading ramp:

No idea what it could be.

Moving further to the north we find German observation post at 57.52304, 28.41792:

Small chamber accessible from the trench and then higher observation tower:

Another observation post is located at 57.64752, 28.22308 in dense forest not so suitable for making pictures:

Note one of the wall is made of concrete "bricks". Those bricks are ca. 2 times larger than standard clay brick and were a kind of standard construction material of the Wehrmacht on the Eastern front. Sometimes steel rods were used as fittings to make a building stronger:

[Eugenius]

Steel fittings are visible here:

Let's get inside, but there is only one chamber there:

The floor was made with tree trunks:

View from inside to the entrance:

A hatchway in the ceiling. Of course, no any ladder remained.

[Eugenius]

Most likely this object had a wooden tower on the roof, for which a hatchway was designed. There are probably tower fittings remained on the roof:

To be continued...

As for me - very interesting. From perspective of Poland, german fortifications "left" Poland in 1941 with most advanced regelbauten series R100 and R500, and "came back" in late 1944 with monocuture of Rs58c/R668/R701. All the evolution connected with eastern front specification happened in Russia and Belarussia (unfortunatelly not much was happening in Ukraine AFAIK).
In terms of identification - pictures are only additional information, basic are drawings with measurements.

[Eugenius]

I should note that most of objects built in Russia were examples of field fortifications built ad hoc, and most of them have no any exact Regelbau reference. The only exception is various Ringstand samples. Additionally those objects were built in hostile conditions and with limited resources. Leningrad region has probably the widest selection of various German fortification objects as frontline south of the city was more or less stable for 1,5 years. But first we will continue with Pskov region...

[Eugenius]

OK, let's continue. This typical shelter/pillbox made of concrete bricks is located at 57.7933, 28.21, on a backyard of local power station or a kind of similar nearly abandoned enterprise:

As usual, all possible pieces of metal were used for reinforcement:

The bunker had 3 windows/embrasures; the entrance is fully buried, so this picture was made through one of windows:

All constructions on top of the roof were added after WWII, when this bunker was used as a basement for stretching a kind of mast or a pipe.

[Eugenius]

Many German objects in the city of Pskov are difficult to explore - they are turned into actually scrapyards and are fully covered with vegetation, almost nothing to see and even less to picture. But there are some exemptions.

This bunker is located near local marshalling yard at 57.80088, 28.35834:

Probably it was used for guarding the railway. The façade was obviously restored not so long ago:

The entrance is blocked with bricks; the only view you may see above of the brick wall is this:

The observation tower was added after the war:

[Eugenius]

This one at 57.79844, 28.42454 was most likely a storage bunker. After the war it was extensively modified with many new entrances built, and finally was turned into a storage by local residents. The remarkable thing is the inscription made on top of former entrance - "Bunker Bulle". As in most of such cases, Bulle was likely a head of detachment, which constructed/operated this bunker:

Another bunker of unknown purpose is located at 57.79571, 28.41849. There is only view from the entrance as all other sides are still banked up:
