I bought the next 14 photos at a yard sale. The guy said his father was a lawyer who dealt with car accidents.
This big black beauty is a 1931 Checker Model M. Notice the unusual front fender shapes and the rear-only running boards.
Looks like a '56 Harley K model Gear shift is on the right side of the bike, rear brake is on the left; this is reverse of every bike I have ever owned. I believe the reason for this configuration is for Harley to sell more transmissions as I smash them during a panic stop.
