Vin, This new site will make it a lot easier for all posters to track the responses. Glad to help, but I hope Curtis can give us some close up pictures. This looks like a UK bike, as 26" wheels were outselling 28's by the late '30's. Could be a big store own name.
It is often claimed that the AW was introduced in 1936, but the K type was still in all the 1937 catalogues. I think the AW was widely sold fairly late in 1937.
The 26" wheel bikes, mainly fully brazed, were taking over from the 28's by 1938 in the UK. Some due to the increase in city traffic, with the 26" wheel the bottom bracket was 1.5 inches lower, so the rider could stop on the saddle with one foot on the ground, whereas on a 28" the 24" frames were too large for most people, and they dismounted to stop. They started with one foot on a pedal and pushed off with the other (like a scooter) then lifted the leg over the saddle. More difficult in traffic.
Thanks for your favourable comments.
