It's a Model 1 with Border Patrol handle and looks like nickel silver guard, which Randall calls the hilt.
Normal hilt material is brass on most, but I think NS is worth the added cost.
If, like me, you don't like the dip in the blade spine, just order the knife built on a Model 5 blade blank & hone the false edge if you want it sharp.
Model 7 is very different, a smaller Model 3. I've owned all three and liked all. I also ordered a Model 1 on the Model 5 blade blank, as described.
And I've owned Models 14 and 16. All are good for the needs for which they're designed.
