I’ve seen that screwdriver on ebay. Doesn’t look right to me. I suspect that it may have been found with a mixed part lot that included a coal loader cover manual with a 1938 copyright date. There are more “1938” sets listed on ebay by seller who assume that the copyright date on those coal loader manual covers is the date of manufacture of the set. The wood handle screwdrivers in pre-war sets have handles that are similar to the handles on tools in the Gilbert Tool Chest Sets. The post war wood handle screwdrivers have a different, sort of bulbous wood handle. But neither looks like the one on that ebay listing. The screwdriver is familiar as I have one kicking around somewhere that has been around since I was a kid. I believe it was either from a Buildo construction set or a kid’s tool set that was not Gilbert.
