Thousands of M-3 White Half-track were converted to M-16's by simply creating a flat floor and adding the quad .50 on a box to raise the .50's so the top sides would not have to be made to fold down as in the true M-16.
The M-3A1 White HT we had in our club (pics on my Webshots) was such a converted M-3 to M-16 and when my buddy bought it, he converted it back to M-3A1. I also have pics of about 200 of these converted M-16's from other models. The were in the yards of the big half-track surplus dealer "Memphis Equipment", just row after row of half-tracks from the Army and southern states National Guard units sold as surplus.
One of the great things about the White Half-track is they were like a giant erector set,a very heay erector set, but pieces unbolted to add or seal up side boxes. Almost no welds on the entire track, just hundreds of armor plated bolts and screws. A truely great vehicle.
Most of the later years had the winch used in place of the roller, but there was always a few rollers floating around in any unit.
I sure hope. I'm right about tomorrows news, but I'll take an M-10, M-7 Priest.......anything.
