Even trying to look for images to see what a 'new' condition knife would look like is proving difficult.

I did find this on ebay of all places, but the blade doesn't to be of an expected shape.  But I cannot compare it to anything either...

One thing I was a little surprised at was that the handle was not smooth.

A couple of things I found that may (or may not) help searches...  Ebonite handle scales, and 'swell end'.  The VAST majority of the 'swell end' Bokers I found had the metal rear bolster/pommel

 You're so right. Back in those days I only had one knife so I carried it everyday. I still have the first knife I ever owned from about 1964. A little John Primble congress that my dad bought me. I have my grandpas knife a Case serpentine and others that all hold a special place for me. I'm sure with more folks now looking I should find some of these. I had seen the one You saw on ebay but it has issues and no smooth handle either. There is a book on Boker knifes that shows these models. Someone on AAPK gave me the info.

Oh sweet! Those guys on AAPK are pretty cool about sharing info...particularly on folders. But then that's in the name...  :-D
