At the time that Blues suggested I build the knife it was far and away the most technically difficult build I had attempted. Even getting the overall "look" and dimensions right was tough. I had no example to hold in my hand and with the Remington being such a rare bird I had no one to ask to give me measurements of theirs. I was glad that the Remington reprinted catalog had some good artwork! Getting the springs , blade, locking bar and spacer thickness correct was a guessing game on my part. Charlie (Waynorth) probably can relate to me asking many times when he would post a picture of a knife to include the all important view knife makers needed, the top down looking at the back spine and the well opening! lol,
I think possibly Schatt and Morgan did a reproduction but if you ever look at one and compare to the Remington a major manufacturing difference becomes apparent. The Lock bar/tab on the Remington is tapered right along with the taper spacer. The S&M made a concession and the lock bar/tab was parallel sided. When I built mine I made it as faithful to the Remington as I could , including the tapered locking bar. I had to borrow a magnetic sine plate from a machine shop in town to grind that taper in on my surface grinder!
The actual build after working out my blade and frame profiles actually was not too terrible and did not leave me permanently scarred as I thought it might, LOL, JK.
Hope this is what you where looking for as far as comment?
