"Landing Legs:
MBT landing leg has 3 positions (3 holes). There was a 1/2 way up position for deep mud use to help support weight of trailer in deep mud conditions.
M100 and M416 only had 2 positions for landing leg - up or down."

I had been thinking that the lunette on our new civilian Bantam was probably from an M100 because I had read that the WWII lunettes were smaller than later versions and ours looks larger than some I had seen on Bantam military trailers.
But, mine has 3 holes. Does that mean it is definitely from an MBT, or were there exceptions to this rule?
The hooks on mine are flat and have the letters "TH" stamped into the sides.
I'd like to know so that if I do decide to trade it off for a civilian hitch I can represent it correctly.
