Brian,
Read the catalog and "non-atalog" description on the Fireman. Wrist thong cames standard on "any" full, exposed tang Randall, i.e. Model #14, #15, #16, #16-Spl. Fighter, and The Fireman.
Compass cannot be installed on any full tang knife, so your extra options are limited.
Thumb notches are standard as well. Hope this helps...
Best, Capt. Chris
