And here, alternatively, is the 'non-standard' pin and catch on Mark Schroeders' L/18 marked Mayer in this thread Not Another EK1 Spange - Opinions Please, which is why I assumed from the obverse, a Mayer....
If this is not a Mayer, I need to up-date my records
IMO the real raptor from Mark looks very much like the Spange from Peter but are not exactly a match. Just look at the date and especially at the "3". I think they're different.
George is of course right and I assume the similarities between the two makers stem from being from the same city (Pforzheim) and probably sharing the same die design(er).
