I’ve acquired a knife I can’t figure out, so hoping someone here can help. I bought it mainly for the somewhat rare stamp, thinking it was a 62001F.

However I got it home and while cleaning and photographing it, I measured it. It is 2-7/8 inches long. I measured it three times!

The books say a 62001 or 6201 should be 2-5/8 inches. As far as I can tell the knife has all the usual traits of being a Case, but I don’t find a 2-7/8 inch Case 2-blade pen anywhere.
Thoughts?

Edit: NM, I figured it out, it’s a 6261F. I’m used to seeing the 61 pattern with a cuticle blade secondary. This one has a file.
