Checking body numbers this morning I find that the body numbers of Webb Smiths '13 runabout and mine are only 323 apart. Mine is F236282 and Webbs is F235959, probably made on the same day! For those that don't know, the F stands for Fisher Body Company.
Sorry guys, I did it twice! I went looking for it and didn't see it, so did it again. Old age I guess.
