Hi Ian,
The M1796 heavy was one of my very first swords, I think I got it in 1966, and it was/is pretty beat up. The scabbard was mismatched (as often found), the blade welded back together at center, and it was by T Craven.
I still have it, couldnt ever let it go

In those days these things were around a hundred bucks usually if in good condition. I think I spent 50, but hey that was a lotta money then....gas was still 27cents a gallon!!!
All the best,
Jim
