Camera ran out of battery before I got all of the photos I wanted.
Here goes with what I have, hope it works (permissions open anyway):
The bar grips are marked Shelton, and the tires are Maloua Sprint (Swiss).
There is a shop decal on the seat tube that says Govuns Cycle Shop on York Rd in Baltimore. Google does not hit that shop at all.
So I am thinking this is probably early 50s vintage.
Any history or other info on this bike would be appreciated. I have never (don't get out much) seen anything like it.
