6-Sch. optics questions
Hi all,
The 6 loopholed turret bunkers must have had the greatest concentration of operational optics found in any single bunker type, and if a percentage of them were lost it would greatly reduce the bunker's effectiveness, but are there any records of how many spare optics were stored in 6-Sch. bunkers to replace battle damaged ones???
I have seen records showing that the gun carriage mounted Pz.Z.F.1 aiming optics were each provided with a spare optic (so 4 were provided in total per 6-Sch.).
But what about the main Pz.Rbl.F. 5 periscope or the 3 x Pz.B.W.F 8 episcopes???
Am I correct in saying that both the periscope and the episcopes have the head unit attached to the scope's main body by breaking plates which allow the head to be 'expendable' if it took battle damage while (hopefully!) the scope's main body can then have a new head fitted to make it usable again.
If this is correct how were these extra heads stored and how many were provided? I have seen photos of a box for holding 3 x replacement heads for the Pz.Rbl.F.5, but for the Pz.B.W.F.8 episcopes???
Any help gratefully received!
Regards,
Malcolm

Re: 6-Sch. optics questions
Hi Malcolm,
I have data on the spare equipment for Pz.Rbl.F. 5, Pz.Z.F. 1 and the S.R. 4.
The files for the Pz.BW.F. 8 (ZN 5909) are not included in the document, but for three Pz.BW.F. 6 there were three spare periscopes, nine spare heads and a lot of smaller spare parts (bolts and metal rings etc.).

Re: 6-Sch. optics questions
Nice Post Malc........and thanks for paraphrasing the "optical density law" I espoused at last years talk.....nice one!
So we knew there might be a "few" replacement heads....but wasn't prepared for quite so many! Many thanks TH for posting.
Again another aspect uncovered here was the use of the SR4 in 20P7 Cupolas.
Really nice to get some corroboration on these points, so far we have been going off of a few photo kindly provided by our friends in Holland of the "Ersatz Ausblickkopfe" case for 2 x Pz.Rbl.F.5 heads (Ausblickkopf).
Another aspect I have been looking into was how disciplined the use of dessicator cartridges (trockenpatrone) were. The inside lid of the Pz.Rbl.F.5. case goes into detail about the schedules for changing them over and drying them out on a heat source so that they change colour when saturated. When dry they were blue but turned red\white when laden with moisture.
Part of my talk last year questioned the seeming "impregnability" of the 6-Sch. yet to my mind......mother nature could happily defeat the position with a few droplets of water
Maybe this is why 6 replacements for the Pz.Rbl.F.5. were on inventory.....and I can easily believe 9 for the Pz.B.W.F.8 based on this approach to scaling.
Thanks again TH a massive leap for us in our learning!
Thanks Malc for the initial post

Re: 6-Sch. optics questions
WOW! Thanks TH That's a lot of optical equipment
So, a 6-Sch would be provided with:
Pz.Rbl.F.5 Periscope x 2 in their boxes (each of which contains the accessories and a spare head) plus 6 more spare heads (held in 2 boxes) [or 2 x periscopes + 8 replacement heads].
Pz.Z.F.1 Aiming optic x 6 (1 plus 2 spare for each gun carriage).
Pz.B.W.F.8 Episcope x 6 (2 boxes of 3) plus 9 replacement heads.
Has anybody ever seen a box/case for holding the Pz.B.W.F episcope's spare heads, or even better a photo of one?
Regards,
Malcolm

Re: 6-Sch. optics questions
Yes, it's a lot of equipment. The document is from 1942, I wonder if the numbers were reduced in later years to avoid shortages.
I've read a general description about that. In the same document it is mentioned that all optical equipment was to be dismounted in times when no combat was expected. Everything was to be stored readily available in the storage boxes at the bottom of the turret.grappener wrote:Another aspect I have been looking into was how disciplined the use of dessicator cartridges (trockenpatrone) were.

Hi TH,TH wrote:. . . In the same document it is mentioned that all optical equipment was to be dismounted in times when no combat was expected. Everything was to be stored readily available in the storage boxes at the bottom of the turret.
Interesting and very helpful, and obvious on a practical level, particularly regarding the heads of the episcopes (Pz.B.W.F's) which would have been constantly exposed to the elements. I was wondering if any records existed for what the optic quota was so the display panels in the Type 634 at Stp. Corbiere gave the correct amount of reserves held (I have had to make some amendments already ), but also to make the correct amount of replica optic cases for display at some point in the future
When the turret room was dug out in the Type 634 at Stp. Corbiere there were several unpainted areas/boxes on the walls (but obviously painted around!) just above the lower platform. Although there are no fixing holes, these unpainted areas suggest that they were the location of storage shelves for the various optic cases.
Below are some photos (by Steve Powell of Festung Guernsey) taken inside the 6-Sch. at Fort Doyle (Guernsey) when it was excavated in January this year, which I was lucky to help with. The bunker consisted of only the turret room and a small room behind it which contained the 'footprints' of irregularly spaced shelving which appears to have been for holding the optic cases rather than the Patronen Kasten Pz.34 ammo boxes.

Malcolm

Re: 6-Sch. optics questions
The 1st photos are taken by me with a Pz.Rbl.F.5 I acquired from the same ebay seller which was tried out in the 20P7 mounted in the 4-Sch.WaKoFest at Wn. La Mare Mill! I had no problems with him and he was very honest regarding the condition of the example I got from him which came complete with its case and a spare head plus some other accessories. The optics are mint as can be seen by the view of La Rocco Tower in St. Ouen's Bayjopaerya wrote:http://www.ebay.com/itm/WWII-German-MG4 ... SwiylXAZ4O

Hi Arthur,AvB wrote:And he's got two of them??
The one now for sale is from a friend of the seller I got mine from. He was surprised to actually see a 2nd example and originally asked if I was interested! From the photos it looks like the breaker plates to connect the head to the optic are broken which is why the head is separate. I have also been offered another recently as well with its transport/storage case but without a spare head
Still looking for a Panzer Rundblick Ziel Fernrohr 3 (Pz.Rbl.Z.F.3) for the M19 though

No it's shown in the '4-Sch. WaKoFest' at La Mare Mill (Val de la Mare) but is normally on display in the 634!
