Can anybody identify this USMC vehicle?

Interestingly enough, Marine Corps publication FMFM 9-2 Amphibious Vehicles dated 1981 provides illustrations and data of both M116 and M116A1 in the Appendixes.  The same pages can be found in the same manual dated 1977.  Whether or not they were still on the Table of Equipment for units or merely held in storage, at the time of the publication the Marine Corps apparently had some available somewhere as late as 1981.  If so desired I can scan and post the pages over the weekend.

There is a brand new M50 Ontos kit by Academy. While some of the hull angles and road wheel arm angles have been criticized, the tracks and suspension should work to some degree for a scratchbuilt M116A1. You may need more than one kit to create a full side of track, I don't know if the length is longer or not.

Yup I think that was it. Too bad nobody makes these as kits. The M56 is an old kit in 1/40 scale.

Those were different vehicles designed by competing companies for the same contract. The Army chose the M56 and the Marines the M50.

I think the M56 90mm Scorpion also shared the chassis of the Ontos.

I believe it shared some components with the M50 Ontos; part of the low ground pressure/airborne capable vehicles developed by the US Army that the Marines decided to buy after the Army decided not to purchase.

That would be a cool little vehicle to model. I guess nobody makes anything like it of course.

Is there anybody who makes anything close. I never even saw a model with the same tracks and wheels.

So many great Vietnam era vehicles and nobody making models of them....oh well.

Here is some more info:

Armored version of the M116 carrier called the XM733, which was called the M116A1 when in service. They came into use in 1966-67. The type of M60 is the M60D, also used on the M48A5 tank.
