I doubt if nayone on TAN can help with a value estimate. There are literally hundreds of old accordions from the 30's and 40's. Having gone to serveral years of accordion swap meets here in Texas. Most go for what the market will bear. Almost none have appreciated in value. Best gve it to an accordion dealer and see if they can sell it. The system only allows so many photos to be uploaded. So two photos is all the can/will be displayed.
