old Schaat & Morgan sleeveboard whittler?

[313 Mike]

This is my first Schaat & Morgan, it was that beautiful bone that lured me in! Crack in the frontside bone and one of the blades is broken off, but I really like the pattern and think it's still a fine looking old knife that obviously has alot of history to it!
3 1/4" closed
Stamped S X M Titusville, PA
Tang stamped on all three blades, main blade on the front, secondary blades on the backside.
Am I correct in my thinking that it is actually a splitback whittler, since looking at the springs it appears the middle liner only extends halfway down the length of the knife, then tapers off?
Does anyone know an approximate age on the knife?
Any comments or info anyone would like to share I'd be most appreciative of...thanks!

Well worth having and that bone is very interesting. Old or new, S&M is a favorite mark of mine.

A beautiful knife, with character.

Thanks for the comments QS and Mr. Rick, I think the bone is pretty interesting too! The jigging pattern seems kind of random...not sure if there is a specific name for the jigging style S&M used...?
Also I just learned that that stamp was used from late 1800's through about 1930, curious if this knife is from the earlier or later part of that range....
