Disclaimer!! There are only 7 of the pistons that match. I contacted Elgin and they identified them as Ford or Mercury, 1939 to 1953, 4” stroke, 4 ring, 3-5/16” bore. There was an 8th piston in the box that doesn't match but appears to be flathead but has no markings other than 040, but a quick measurement shows it is close to 3-3/16". PM or email with an offer. Maybe use for piston art?
