Emilbush 4078bb vs Emilbush 1340b


Hello,
we can notice that on my glasses for Gewher 4078bb, there are 2 different numbers on the mount, the 4078 (height 2.5 mm) only on the front support and the 232 (height 3 mm) on the front support and on the rear support. you can also see the letter b on the front support and the rear support
A French friend has the same set as mine for the 1340 b rifle, she's in very good condition

The numbering of its feet is different, the number 1340 is carried over to the front mount and the rear mount.
I come back to mine, 4078 bb, is the number 232 (3mm character) a machining number? or is that the riflescope could have been reassembled on another rifle, in any case the number 3 (232) is the same on the 4078bb and the 1340b and the 4 both have a small bar at the bottom, therefore certainly struck in the same workshop, we also remake that the bottom of numbers 4078 and 232 is blued every 2 so strike before tanning, mine also has the letter B on the faces of the 2 mounts
I guess my friend's scope were for a dantzig from 1918, a letter b from 1917 would be too soon for this mount, well that's my opinion, do you agree with me?
thank you for your's answer

very nice thanks for sharing
