I'm going to hold onto my "Options Quota" and go with a Brass Square Top hilt. I'll add my own Thumb Notches with my checkering file.

OK Crew:
So....after seeing what others would wish for, let's decide on the hilt-n-spacers (as one might determine the other). Not carved-in-stone yet, but let's see who's burning options and who isn't. We need to proceed at this point.
Model #3's "can" be built with double hilts, brass or ns. They can have the standard (rounded) single hilt or "squared top" (N/C and it doesn't count as on option).
Spacers? Red, white & blue, all red, all black are @ N/C also. Brass-n-red, brass-n-black, alum.-n-red, alum.-n-black, brass collar or ns collar will cost you an option...just sayin/ Let's roll!

Black spacer

TN (Counts as an Option?) But I would yield on this depending on how the handle might get built out.

Black and Brass spacers (A chargeable option)

Nickel Silver squared

NS hilt (standard shape)
standard spacers (why use up an option here?)

Standard Spacers.
Nickel Silver Hilt / Rounded.
(I feel the rounded hilt works better with the nicely curved top of the #3 blade).
