All About Pocket Knives

Hello
I am having difficulty in identifying this case knife.
Could you please help?

to AAPK, Jinsail. Not sure about the originality of the stag handles/scales, but I have a few reference books at home, mainly by Jim Sargent, that have old and obscure Case patterns listed and pictured. Could be the first 5376 ½ I've ever seen, thanks for posting.

The pattern number identifies it as a 5376 1/2 stag handled whittler. The Bradford stamp dates the knife to approximately 1920 or earlier. This pattern was discontinued in the tested era. Would like to see a picture of the entire knife. Is the blade that isn't shown entirely stamped?

Sargent's 4th Edition has one listed on Page 95.
