I picked up a 3-speed BSA bike in 21" step-thru frame for $13 (priced at $15) at a neighborhood garage sale for my father in-law this morning. The bike is made in England with a leather Brooks saddle and a leather tool bag attached to the saddle. The bike has front and rear fenders as well as a chain guard. Tires are 26" x 1 3/8" and have markings of 37-590 and 55lbs/in2 - 3.8 ATM (not sure wat the 3.8 ATM means) along with the word coaster. It looks in pretty good condition with a few minor rust spots on the fenders, but otherwise looks great.
According to Sheldon Brown's site:
B.S.A. (Birmingham Small Arms) was an important independent manufacturer until the bicycle division was sold to Raleigh in 1957. Originally an armaments company, their logo represents 3 military *****s stacked in a tripod.
So do you think this is a good find? Anyone know the approximate year of this bike? Can I assume from Sheldon's site that the bike is before 1957 since BSA was sold to Raleigh then or did Raleigh still manufacture bikes under the BSA name? The seller, who looked to be in her early-to-mid 50's said it was a bike she used during her high school days.
