My 1ST Bridgestone was a 1967 50cc ( Homer/Step-Thru).
I was 14 & bought it on a payment plan from J.C. Penny Automotive Center in Weatherford, Texas. I think it cost around $220 new, & I made monthly payments of about $15 per month. I washed all the family dishes (the old way) for 2 years to make payments!!
My Brother-in-law let me put the bike purchase on his J.C. Penny charge card, as my parents had no charge cards. I got it all paid off & really enjoyed that little Bridgestone until I eventually outgrew it... I got my 1st Drivers License riding that little bike at age 14....
Now I have many vintage Japanese, British & Italian bikes, including 10 various model Bridgestones, mostly resto projects for the future, since I just retired last year.
Sorry for rambling on!!!
