It's an Armstrong, which may be the only part of his info that is correct. It isn't "circa 1950's" as he stated. It's just a 60's english bike in decent condition. A basic internet search of the brand doesn't show them to be any better than other British bikes of the period. But he is convinced that it is quite valuable. I'd hate to see him get a hold of a prewar bike.Looks like a C.C.M., and i remember you posting before! I can only imagine the person buys and sells used bikes, otherwise they'd give up!
