All About Pocket Knives

Not on any of the charts.

Looks like the one on the chart Sheppard Hills has for 1920-1940 ---> http://casexx.com/Library/TangStamp.asp
But that differs from the one on AAPK's site for the same era ---> https://www.allaboutpocketknives.com/co ... ification/

That’s a fairly rare stamp. Here’s a picture from Sargent’s, 7th edition, page 34.

And one from Witcher’s Counterfeiting Antique Cutlery section on Case family tang stamps. Note that Witcher says it is commonly seen on Tadpoles, such as the OP knife. I may have a Tadpole with that stamp - I’ll have to look for it.

Edit: Steve it looks like we were both posting at the same time! The tang stamp listings here on AAPK have the more common stamps but are far from comprehensive. Probably the most thorough listings of Case stamps I’ve seen are in Witcher’s and Goins’ books. Witcher has photos of many in addition to artists renderings seen in most sources.

Very unusual to see a 29 pattern knife with just one blade. Normally seen as a 6229 two blade tadpole. If the knife is correct that would make it a very hard to find pattern 6129.
