A & A MFG Co, Germany razor identification help

Can anyone give me any information on this razor.

It has A&A MFG Co, Germany stamped on the tang.
It has wooden scales and a nut and bolt instead of a solid brass pin.

Any ideas on it's age, would the scales be original and would the nut and bolts be original.

This is the razor I want to restore next, if the nuts and bolts are original will I cause any damage by undoing them and cleaning etc and then putting it back together.
