Dan,

That's a pretty Model #1.

If the ST Grind with No ST is a chargeable option I would say you have 8 options there and if not 7 options.

1. SS Blade
2. ST No ST Grind ?????
3. NS Std Double Hilt
4. Metal and Fiber Spacers
5. Stage Handle
6. Finger Grooves
7. Duralumin Butt Cap
8. Thong Hole

Good Find!
