My RAD is getting out of control (nearly literally). Today it compelled me to buy this razor that I couldn't find any information on at all:
I searched B&B and Google endlessly, and here's the closest I've gotten:
Link1 (Post #7) - Albeit a different end cap on the handle
Link2 - Bakelite version, red box.
So it would seem it's a non-adjustable Progress. Is this correct? Any idea about the time frame in which Merkur used blue boxes? Thanks for any help.
