Anybody heard of this maker??

[Fixed Blade]

I recently picked up a rather unusual large Stag Handled Hunting/Fighting knife. Has a "flint-knapped" type blade. Overall style is Randall. Only markings are "ACE" engraved on the guard. Don't know if that's maker or prior owner?? Superb quality with the largest piece of Sambar stag handle I've seen. Anybody heard of "ACE"?? I'll have a picture taken by tonite and add it to Post.
