I have a Schatt and Morgan with the same frame, a 2 blade with bone. I'd call it a "teardrop". M & G had knives made by S & M, Queen, Schrade, and Miller Bros. Hard to say which but the handle sure looks like my S&M. What's it's length and thickness at the fattest part? Good luck.It's a very cool piece. J.O'.
Probably Miller Brothers or Ulster.I've not observed a M&G that was Schatt and Morgan made.Schrade made one's started appearing in the 40's and Queen in the 60's and 70's.
