Since taking this pic, I've discovered it's approximate birth date.. It seems that during the war years, chrome or nickel was rationed for the war effort, so these bikes were sold with minimal plating.. just seat post and handlebar stem were plated, everything else (except the wheels) being black enamel. I quite like the utilitarian look though!
The lack of any date stamped on the Sturmey archer AW hub would also indicate wartime production. It's a Raleigh shape frame which puts it after 1943, when raleigh acquired Rudge from EMI. So 1943-45 is my best guess so far!

There are notes on the parts that are new. Kept the original chain ring, derailleurs, cranks, brakes, seatpost, and shifters. Replaced the bottom bracket, wheels, brake levers, seat, stem, bars, and pedals. Brake levers, grips, wheels, and pedals are repurposed from other peoples' bikes.
