@Absalom,
My judgement is not based on opinion. I know five basic types of magazines.
1. blued, pinned baseplate, holes in a straight line
2. nickel / chrome, pinned base plate, holes in a straight line
3. blued, pinned baseplate, holes staggered
4. nickel / chrome, pinned base plate, holes staggered
5. mate nickel, patented base plate, holes staggered
German Patent No. 393629 (09 April 1921) was granted 9 April 1921. The patent describes the method of construction wherein the lower edges of the sides of the magazine form flanges that wrap around the base plate to hold it on. Thus, if we find these magazines in guns prior to early 1921 one can for sure say that they are mismatched.
In my collection I do have 14 7.65mm or 9mm Ortgies of which some have the button safety or can be attributed to service use due to stamping.
Serial number | magazine finish | staggering of holes | base plate | comment |
1 | blued | straight | pinned | prototype |
1491 | nickel | staggered | patented | 9mm, button safety, due to slide legend a fifth variant pistol, possibly numbered in a separate SN batch |
2324 | blued | straight | pinned | commercial |
4283 | nickel | staggered | patented | Dutch government contract, mismatched magazine |
13380 | blued | straight | pinned | commercial |
27831 | nickel | staggered | pinned | button safety, blued spare magazine, unit marking S.K. 2 |
29900 | nickel | straight | pinned | commercial |
36220 | nickel | straight | pinned | commercial |
40000 | nickel | staggered | pinned | commercial |
53336 | nickel | staggered | patented | commercial |
61666 | blued | straight | pinned | button safety |
66768 | nickel | staggered | patented | commercial |
81042 | nickel | straight | patented | commercial |
249859 | nickel | staggered | patented | commercial |
What one can say is that due to the patent 393629 all guns before that date should have pinned baseplate magazines. One finds pinned magazines with polished nickel or blued finish, straight and staggered holes.
I cannot clearly attribute blued magazines to service use and nickel ones to commercial use. Especially with early service and commercial guns, we find either blued or nickel ones with pinned baseplates. Additionally, we also find service guns with nickel magazines with the patented baseplate.
Thus, I must say that the Deutsche Gesellschaft für Polizeigeschichte is wrong with its absolute distinction of magazine types used in commercial and service guns.
