Schwinn Bantam, Murray(?)
I picked these up for 35 clams. The first appears to be a Schwinn Bantam, minus a wheel and fenders, but including the top bar. Previous owner said all parts except tire are original. Bad shape. The second he thought was a Murray, but it has a terrible paint job obfuscating the decals so it's hard to tell. As I recall he said it has all original components, minus the paint job and saddle (Huffy). It needs a new chain, and probably rubber. The wheels are in especially bad condition: tight hub and broken spoke on the rear, and missing axle nut on the front. The bottom bracket and headset could use overhauls. The fenders are banged up and rusty on the bottoms.
Are they worth anything?
Given the condition, there isn't much value to be had.
Cleaned up, you might get around $50 for the Murry.
those bantam removable top tubes go for 20 bucks on ebay some times. the seats bring about the same if they are the original messinger style. parted out is probably the best bet to get money from it.
no opinion on the murry but the monkey hanger bars are nice
