M113 Tow Bar

I located one of these items. Is there a market for these?
This one is new..

Whats the NSN? Is it a Medium or a Heavy? Heavy's need 2 people minimum to lift. Mediums can be done with 1 guy with some difficulty, heavies guarantee you'll give yourself a hernia trying to lift them yourself.

If it is put together it is a two person. One person will strain, with just one piece.

That would be good for someone with an M548 cargo track....same chassis as M113....
