Identified in two 1950s Merkur catalogues as the Merkur 71 (the white one at least, I suspect the brown to be one too), these are nice little lightweight (26 gramms, 10 of which in the cap alone) razors with the familiar Progress-like baseplate.
The ridges of the safetybar on the brown one are flattened, ont the white one rounded. Also, the white one has a Merkurlogo one the bottom of the handle, the brown one has a hollow handle.
