I believe it is a Murray made for sears.
it is all chrome
double top barr
under bottom rack has:
MOD50246160
370072


I also have a couple Columbia frames 50's era but the rear of the frames have some differences. Where are the numbers located on these?

Thanks for your help!!!

Nice bikes! The Sears has a Monark chain wheel and the older Columbia has a Rollfast 60's chain wheel. I'm not sure where the serial number will be on that one, with the rear facing dropouts. I think I saw that bike or one just like it somewhere recently.

On the Columbias, the number will be on the left dropout. The font and depth is less than most bikes so they might be hard to see. They should start with a letter that will ID the year.
Ok. Thanks I will try and locate it there
