A local thrift shop had one of these, sorry but no pics. It had a headbadge that said Foremost. Seat tube sticker said something along the lines of Guaranteed Lightweight (or something like that). Steel front fender, raised center ridge ahead of the fork, big dent in the fender behind the fork. Missing the rear fender and chain guard. 3speed rear with just the shift chain dangling, no cable, no shifter, I didn't check for brand or year. Wheel bearings were sloppy loose front and rear. Cottered cranks. Steel 26"x1-3/8" wheels. Non-descript coil sprung seat with manmade cover material. Upright handlebars. I don't recall if the brakes were center or side pulls since by that point I'd already decided to pass on it in spite of the sub-$15 price tag.
Just posting an inquiry about the Foremost brand, I'm thinking they were a side brand or re-badged from the bike boom era. Ust looking for a little Foremost history out of curiosity.
