bit late on this thread.
Most has been said but I think your zinc clasp with 200 hanger could be an unmarked RSS.
I like the early bronze tombac piece as like Ned mentions it could be an unmarked Juncker.
All the best
Thanks Doug, if the price of the first one was not 335 Euros, I would buy it, but as Stewy said it s over the top and I always try to pay a sort of fair price
