Bunker optics

Hi All,

thought it was perhaps interesting to start a topic on bunker optics.
Don't think we ever discussed this topic extensively. I will post some pics
later on !

Recomend adding a measure to that sort of photograph. How wide are the boards in the floor? From that I can estimate the size of the scope.

What magification does it have?

Hi,

the device is 28cm long, diameter is 28mm..
the magnification is 2,5 x 19o

I think peter knows the whereabouts of those optics

Peter was the optic that u posted placed upon a tripod? I have seen similar models on tripods.

Regards,

Robin

Hi,

Indeed I know the whereabouts...

The photo was made on the diningroom table of my parents house.
There are indeed several lenghts of this type of optic.
For example the Pz.B.W.F.12 was used in 486P2 turrets.

The Pz.B.W.F.5 was not really used on a tripod. They were placed on a special plate
which could be mounted to a fixation on the turret wall. The optic looks a bit like a
Richtkreis, perhaps that is want you mean. Apparantly the Pz.B.W.5 was used in pairs
in the 89P9 turret. There is also a second type of the Pz.B.W. 5-optic, which can be seen
on Robert Jurga's drawing of this turret. Because the head of my periscope is slightly damaged
I don't know if the exact designation could be 5a for this type and 5 for the 'Jurga' one

Cheers,

Peter

Will try and look for a photo of the mounting-plate.

Since the turrets of PzKw38(t) was used on bunkers, I guess it`s ok to add this:

P.Z.F.38.(t)

Erik. Nice picture. Do you have a photo of the optic installed
in the turret?

Hi,

Too bad, but if I'm not mistaken there are still loads of these turrets
around so perhaps one day we can see it in an exhibtion.

Btw, are you comming to the Atlantikwall symposium in Raversijde?

Hallo,

The Pz Winkel optics (Z-shape in Uk?) for fixed fortifications,
come in two versions, I think.
1. The Busch type has, as far as known, four different
lengths, numbered 7, 8, 9 and 12.
The higher the number, the shorter, so the thinner the cupola/plate.
See the pic "collection" of Bunkerbehoud.

2. The Zeiss types exist at least in three lengths.
See the pic "zeiss" taken from their website.

The pic "shop" shows a PzB.W.F. 9, taken fully apart to
clean it from the "fungus opticalus germanicus", an organisme
that feeds on the minerals in the glass. The result of this parasite
after over 60 years, can be seen in the item on the M132 on the
Channel Islands.
(to be continued in the next entry)

Lenco,

Hallo,

It goes on.

Chazettes "Armements et Ouvrages" on page 33, shows the
sorts of mountings for Busch and Zeiss.
The Busch mounting, the birds-bill, is shown in the pics
below.

Has anyone pics of the Zeiss mounting ?

Lenco,

Lenco,

If i remember correctly the turret (61P8) of Stavanger has the Zeiss mounting still in place..
Perhaps Erik E or Erik R can post an exterior photo of this mounting
I think it's also featured on the picture cd enclosed with their book

Check your own website!

Panzeratlas -> Dreischartentürme -> 61P8 and 60P8 (first 2 pictures).
I got some detail shots I think.
