I gave this AMC FLASH to my Brother in Law and he added a motor

I had the motor and tank on another bike it is not a runner just yet but Im sure it will be. I had the bike hanging in my barn for about 10 years he fell in love with the OLD SKOOL look and had to have it. The AMC is a bike made in the 50s and 60s by Shwinn HMMMM? Maybe shoulda kept it?? LOL
