There's a guy on eBay selling those, he says they're made of Zamak, and it sure looks like some kind of zinc alloy.
Oxford razor, made in England:
I bought this razor from a chap in France. I have very little information on it.
The handle screws into a small recess on the bottom plate.
I think it's a nice looking razor, and I would guess that it was probably made in the 1930's?
More information would be greatly appreciated!
