Dot 1945 coded receivers.

[mauser99]

interesting topic and one I enjoyed reading again almost 10 years later. As far as the 4 being removed and the 5 added this doesn't seem to be the case as these dates are stamped very deep and I would assume that grinding the 4 away to add a 5 would cause a noticeable dip in the receiver. We all know Brunn 1 did another absurd thing with the 945/41 receivers choosing to shelf them instead of using them up in 41 after that code change so the dot45 to swp45 makes sense even at this late stage. The Czechs post war were the first to take advantage to any new war and sold lots of supplies and planes to the state of Israel in the first war. I mentioned before somewhere else there was an interesting documentary on this subject on net flix. These type set dates are Indvidual digits and we see elsewhere where the dates are abbreviated for possible later use ? IE bcd bnz 4 marked receivers.

945/41 is not absurd thing, because 945 was used 1940, not all receivers were used, there is no problem with, because they known in ZB that the german contracts would continue.
The 1945 die stamp presented here by mrfarb is evidently that the base is 194 and the 5 is here in upper position, when You look at piece presented in vol.III pg.269, You will find that the last 5 is in lower position to 194 base so i must assume the last 5 was there added into the stamp and was movable to other 3 previous digits 194. The origin 1944 date was upgraded to 1945 evidently by using older stamp. The piece on pg.269 is serialed 4635a and is CS lion proofed, so i should assume this type of marking was postwar.
I added to contrary the last one dot 1945 piece with last digit 5 in lower position, with no right side border stamp, the barell has a rejection stamp, so was mostly from older german rejected production. The last one have outdoted CS lion fire proofs with no presence of older german fireproofs so are certainly postwar production. later refurbished in Israel offcoarse.

My understanding of what Andy said was that the dot 1944 stamping die itself was modified by removing the 4 and manually adding the 5 and then stamping new receivers with the modified dot 194 die, not removing the 4 from previously stamped 1944 receivers. Assuming this was done prior to the swp code being ordered and the dot 1945 ones set aside till postwar.

I believe from the real pieces even not seen even the presented mrfarb (Mike?) piece, that the changed dot1945 stamp was used postwar, as both samples in book and here the israeli used are postwar production.
personally i never seen a period dot 1945 stamp with real german fireproofs so i would tend to opinion dot1944 switched directly to swp45 as is visible on the serial range in a letter. In case we will find so period pieces Your opinion could be real.
From the serial page:
dot 1944 42488a
swp 45 43026a earliest reported swp 45
dot 1944 43125a
dot 1944 43241a
swp 45 44606a
dot 1944 45238a latest reported dot 1944
swp 45 45306a
swp 45 45583a
Also nothing strange to see the switch from one to other code was done in range of 2000 pcs.
Postwar czechoslovak started a new range string of serials in Brno, and i assume they used swp45, dot 1945 and dou45 stamps to hide the new production and should be declared as remains of german production parts, which should be already unreal by the numbers produced and reported.
