From the tank maybe late 40s early 50s.
 
the frame/fork alone look 50s w/ the drop outs and the seat stay. but the fork looks bent.
but the kickstand mount looks much later. the stem (besides being backwards :lol: )looks 70s.
the chaingard aint 50s Columbia. the sprocket is modern(not skiptooth) so it's at least mid 50s and up, but it is a Columbia sprocket.
the pedals have reflectors so they're mid 70s.
seat is probably 60s or 70s.
that's all I can see right now. lt's a frankenbike. perfect platform for a bad daddy custom.
