I saw this photo on another site. Looks like a very early M4A1 (with M-3 suspension) with add on armor, sand bag racks and a rebuilt turret with the commander's cupola. I seem to remember that there were issues with the M3 suspension not holding up with the Sherman's weight. I would have thought that by 45 any old hulls like that (that hadn't been destroyed) would have had the suspesion upgraded when all the other changes were done.
