That looks like no known rocket that I have seen. Peter Alway could chime in and answer it more definitively though.
My guess is that it is an amateur/experimental rocket. The fins appear to be plywood (or some kind of wood), and most of the "real rocket science" of the era was all metal construction. There doesn't appear to be a recovery system and the motor, I don't know know what to make of it.
Regardless, I am sure that there is a very interesting story behind it.
