I picked up this set of 8 Craftsman Professional lathe chisels recently. These chisels have 10" maple handles.
I'm pretty sure this set is listed in the 1948 & 1949 CM Power Tools catalog ('49 catalog entry included below). The handle size is correct and the box is wrapped in artificial leather. 1949 is the last time (that I can find) that the "Professional" set appeared in a catalog. Earlier catalogs (1940 & 1943) list the set as coming in a "Heavy wood box"; there is no mention of faux leather wrapping. But, I could find no other catalogs with wood lathe chisel between 1944 and 1947, so I don't know when the faux leather wrap started.
(Edit 12/1/24: The 1947 Sears Christmas catalog included the Heavy Duty Professional chisels in a artificial leather wrapped box.)
My set has the long-C badge on the box. I have seen other leather boxes on eBay or GJ with the heritage badge though. The inside of the lid also has a unique stylized long-C font. The description of the tools (on the inside of the lid) mentions they are vanadium.
I think my set may be the end of the run for the 10" handles, because it appears to be a mix and match set. In my set the handles have two different stickers. There is an oval sticker that is blue/green/yellow with the long-C underlining "Craftsman Tools" on 2 of the handles. The others all have stickers in the shape of the heritage logo, that are blue/yellow/cream.
There is also a difference in the fonts of the stampings on the blades (pic attached). The stamping on the 3/4" Gouge has the same stylized C as the one that appears on the inside of the box lid. The font is also stylized in the word "Professional" (take note of the S). The 3/4" Gouge has the heritage style logo. However, the 1" Skew also has the heritage style sticker, but the stamping font is different. Lastly, the chisels with the oval sticker all have a font similar to the 1" Skew. All the chisels are stamped "BP U.S.A".
As for the badge on the box: I saw a lathe for sale on FBMP that has the same badge (shape and color scheme).
I picked this set up for $65 and it doesn't look like its ever been used. The chisels are factory sharp and there is no sign that any have been resharpened. There is crazing on the handles and any wear seems to be from being jostled around in the box. The faux leather has some heavy wear in places, but the box did its job and protected the chisels inside.
*There are sets on eBay, in the same style box with the reddish brown handles. The handles (not the blades) are marked "Professional", but look shorter than my handles. Also, some of the boxes with these chisels are labeled "Professional" (Like my box below). These sets all have the final heritage badge and stickers and the boxes are wrapped in faux leather.
