Ah yes, I see...
I don't really aprove of google so try to use Yahoo or bing, but they are fecking awful in comparison.
Can't believe I didn't realise the relevance of C12/C16... I'm going to blame coming down with the cold

Heres a clearer picture, without the flash.
Every blade is marked with a big curved 'REMANIT' and 'Rost Frei' above.
I can't see any makers mark, but the main blade has a 'A' on one side of the remanit logo and an 'L' cradling an 'R' (if that makes sense) on the other.
The file/chisel blade doubles as a lock release for the main blade when its closed.
The frame is made of brass sheets and nickel mounts, the slabs are very finely sliced stag horn.
So, do we now think nearer the begining of the C or still more like 1950s?
OH, and whats the hole in the hoof pick for?
