A R.S.& S Aluminum

Most of the nickel Bahnschutz are Assmann but the larger ears, longer prongs and the smooth reverse might make this one a Overhoff & Cie.

A couple of nickel Assmann buckles. I have moved the lesser condition one but this shows the difference in finish from the silver paint to the base buckle.

Another Wasser Reichbahn but with a gold washed finish as seen on Water/Traffic Police buckles.
