Look closely at the coin entry on this slot machine.
It is the wrong one.
This coin entry goes on the later style where the housing on the top casting wraps around the coin entry..or ... the coin entry sits down in the housing for the coin entry... however you want to word it.
Look close... the mech has National reel strips.
National Novelty was at 513 - 519 Third Street South, Minneapolis, Minnesota.
