The M201 Pintle hook has a safety pin to prevent the jaws from opening. The MB is very similar, but without the pin. The Ford GPW pintle hook has a script 'f' on the right side.

Hotchkiss Jeeps had a number plate light mounted under the jerry can bracket. The MB and GPW Jeeps don't.

On the M201, because of the metal hoop supports around the windscreen wipers, the screen doesn't sit as low on the hood when folded down. As a result, the clamps are raised off the hood on small blocks to give the extra height required. On the MB and GPW, the screen rests on the wooden blocks attached to the hood, and the clamps are bolted directly to the hood.

The M201 steering column clamps are bolted to the dash. On the MB and GPW, the clamp is riveted.

There is a small triangle fillet on the front edge of the rear wheel arch. On the MB and GPW, this is part of the side wall which is folded over. On all the M201's I've seen, this is a separate part, welded in. I don't know whether this was designed, or whether is was as a result of cutting through the seams and edges of wheel arches during factory recycling of parts.

Willys and early Hotchkiss Jeeps both had canvas seats and roof. Hotchkiss later changed their seats and roof for a vinyl material that would wipe dry. On the M201, the rear window opening was also fitted with a clear vinyl panel. The MB shown here has a summer roof canvas fitted. The GPW has the winter canvas set which includes rear side panels and full doors.

The Hotchkiss mirror was enlarged to a more rectangular form from the original round MB and GPW mirrors. The MB & GPW mirrors have a central fixing bolt and a lip around the mirror frame. My GPW has a mirror the same size, but with an off centre fixing and a smooth convex frame. It is similar to the later Willys M151 Jeep mirror. The M151 type also has an offset fixing, but that has a lip around the outside of the frame like the MB mirror.

The Hotchkiss Blackout light has a much flatter housing than the MB and GPW light, and the shroud is tapered. The Ford light has the Ford elliptical logo on the front.

On the M201, the butterfly nuts on the screen and hood bows have a slightly different chain and attaching method. The Ford bracket is 'f' stamped, as is the front bow support.

On the M201, the side grab handle is a short, more angular design, but with longer mounting flanges. The the Willys and Ford handles have a longer more rounded handle, with shorter flanges. The rear corner handles appear to be identical. The Ford handles are 'f' stamped on the mounting flange.
