Thread: Unknown razors - does anyone recognise?

I have four unidentified razors, and wonder if the members know anything about them. Three of them are here:



The first is a pretty heavy 6/8 blade, and looks to be stramped 'Ramon Paris' on the front, with no stamp on the reverse:



The second is a light 3/8 blade, and is stamped 'RK Paris' with a backwards R on the front, and 'A RÖHNER PLAUEN' on the reverse:



The third is marked '5101 IDEAL' on the face and 'L.P.' in an oval on the reverse:



Could this be a Louis Perlman budget razor? I say budget, because the scales seem to be some sort of cardboard; there is a tiny bit of black paint on one part, but this finish has otherwise come off. As an aside, does anyone know how to make this type of scale serviceable?



Lastly, there is a Wiener Schaber stamped '43 Wiener Schaber' on the front, and 'KAROLUS' on the reverse:



Curious to know if any members know the origins of these razors. The first one looks like a nice old-school blade, I'm looking forward to trying it.
