OK guys, I will solve the little puzzle!
Hello I ment RLSV Reich Luftsport Verband. This is only the second type of army buckle I have seen with RZM markings. Kirby
Only joking. Rather like yourself, I tend not to search by markings. Ironically though, I do look out for variation Assmann markings to their early nickle silver HJ's. Of course, not exactly the most difficult task to secure a HJ buckle which displays the famous Assmann logo.
A remarkably unorthodox set of markings for this particular buckle.
Anyway, talking about St. & L. markings, how about this one?
Hello I forgot about this Assman buckle. I had it in a dagger display. So I do have another trademarked HJ buckle. The catch is missing.
