When I took the daggers apart, I found the following:
- small double oval TM - tapered tang
- large double oval TM - wouldn't come apart
- small single oval TM - tang marked with a '+' inside of a square
- large single oval TM - no markings or anything unusual.
Based on this, I would guesstimeate the chronology of marks as above, with the small double oval as the first one used.
Anyone have nay other ideas?
