Hi,
the good news is that these look very much like the german army Fero D12 made by Steiner which was still being used in the german army when I was serving in the early 90s (the last model w/o) laser filters for whatever reason) - after all the Leopard 2 tanks which I was working on back then had laser rangefinders since their introduction in 1979...
The bad news is that these bins were not well loved by anybody besides some beancounters and my comrades in the optics repair department always had a case of beer or two to share which they got from those who still had the preceding Hensoldt DF and needed repairs for those.
By the book these were to be sent back to the depot to be either stored for WW3 or destroyed for decades...
But nobody wanted a plastic Steiner with soso optics in return for the built like a tank Hensoldt which is still a nice cheap pair even today - and so cases of beer were offered for clandestine repairs with scrounged parts and those pairs which were beyond repair were carefully disassembled for parts...
Holger Merlitz did a review of the Fero D12 vs the Hensoldt DF and some very rare Zeiss West DF which was never adopted (which is interesting since obviously two companies belonging to the Carl Zeiss foundation competed against each other back then for the german army tender...
Joachim, who has pair of Hensoldt DF 8x30 with the recticle removed in the glovebox... the best 50€ I ever spent on optics...
