Phrobis III parts source? + FMV question

[K1196A]

I have both a narrow and a wide font 4th gen Phrobis III. I was curious, all things being equal in terms of condition, which is worth more and what is a FMV? I'd estimate both to be in excellent condition (minus 1-2 caveats on the wide).

That raises my other question -- is there any source for replacement parts? I need to replace the chipped wire cutter on the wide and get it a pouch for the front.

Was a 4th gen Phrobis ever issued with the later style wire cutter, or would that being present on a scabbard represent a unit repair?

Thanks.
