Lee/Grant Tractor

I ran cross this uncredited photo on the web the other day and am wondering who was using this vehicle, what is it towing and where and when this photo might have been taken.

Looks like a chalk, or hand painted. loading code on the right front fender but not much else in the way of markings and looks like a sizeable superstructure added to the outer sides of the rear deck area. Stowage perhaps.

M33 Prime Mover

One source states the photo above was made in Italy in 1944.

An internet search yielded this:
Quote:

The M33 Prime Mover was a tank recovery vehicle M31 that had its turret, winch, armament, and crane removed. This was used instead as a tractor for the towed 8" gun and 240mm howitzer until the 38-ton high-speed tractor M6 could be fielded. Canvas covers were carried for the turret and machine gun mount openings. (Picture from Catalogue of Standard Ordnance Items, second edition 1944, volume I: Tank and Automotive.)

Thank you Hanno,
My first reaction (based on memory) was that it was a recovery vehicle based on the dummy gun and the rear deck stowage but I didn't have references to back this impression...

That one is fairly easy: the barrel of a 240 mm howitzer M1:

To move it, this weapon was carried on two trailers, one with the barrel like here, and another with the mounting.

Those are standard stowage bins for an M31 tank recovery vehicle:

(The bins are open here, they’re normally closed with lids.) The M33 prime mover is basically an M31 with its turret (which carried the crane) and much of the recovery equipment removed.

Hi Hanno,

This official file says "no winch" but we can see a little bit of the winch on the photo, so ???

Cheers,
Patrice.

Well, it is a recovery vehicle converted into a towing vehicle, so in a sense you're right.

Hi Patrice, indeed the version of the photo on Sherman Minutia clearly show the winch was left fitted in the hull. It most likely came in handy to position the gun.
