I might be wrong but IMO its looks like 55 Hammer&Sohne,but please wait when experienced guys jumps in!

[BTR]

Perhaps I missed something, but it seems to me that he does not look like 55.
I suppose, if the specialists are silent, it is probably a difficult case even for them.

Klein und Quenzer. Probably a Type A Core.

Thanks for the help.
