Automoto built frame bike from around 1930. I believe this was a contract build by Automoto for another company. I know they did that, but how many different brands used their frames is a mystery to me. It should have rivet holes for an Automoto head badge if originally badged as such since all their bikes had metal plate badges to my knowledge; certainly bikes of this era did. The Mosca chainwheel is a mystery (French or Italian?); bottom bracket is French, but cranks could have been replacements, as well as the BB itself. Bowden style steel caliper brakes (mismatched brands) front (French made; says "FREIN depose") and rear (stamped "SUBLIME", country ?). Very old French saddle that I can't quite ID. I'll try to give more info and photos in short order.
