Sherman m4a3e2

Here is a picture of my M4A3E2 "Jumbo" you can get a good idea of the glacis thickness by looking at the keyhole cut for the bow gun, as well as how much thicker it is than a non-jumbo differential which is installed in this case so we could throw tracks on it and have it sit for static display until we get around to it's restoration...it is #73 of 254 built, one of only 6 or seven left in the world, and I am sure the only one in Canada.

Regarding headlights, the original glacis under the extra armor plate has no holes for headlights either, some Jumbo's do have the headlight holes under the armor plate...some don't...very odd

Don't forget that most Jumbos were not conversions of existing tanks but were built new as M4 A3 E2 standard. However, as far as possible existing designs of components were used so that design and tooling work were minimised. Where it was easy to not drill a hole or weld a piece on (like the provision for the headlight sockets) they took the opportunity but if they were short of a particular piece (the simplified glacis plate here) it might well have been easier to use a standard one to avoid waiting for a delivery. They might easily have had to take part built hull fabrications that were intended to be standard M4A3 off the main production line and finnish them as M4A3E2 hulls.

inside the hull is all the mounts for the exact same wiring harness as the standard M4A3 with headlights, just nowhere for the leads to go...I believe in Cobra King they found it had a standard M4A3 wiring harness with headlights but again, no holes for the lights...surprising they did not just fabricate a bracket off the fender or somewhere to mount the lights...moving at night in a convoy during the march to Bastogne must have been exciting with not even a convoy light...I guess you just follow the tail lights of the tank in front and let a tank with headlights take point

In the first photo, Bastogne, they appear to be using a crew commander spotlight with no blackout cover, solves the no headlight problem.

Wouldn't think you could use that at night in convoy situation, probably cause more harm than good no?

[Wayne Henderson]

The picture of the Bastogne tank has the light fitted, not much use in daytime.
With the shroud fitted you can get very good results and if they are using the trigger grip mount even better.

As I understand it, these were built as assault tanks for the specific purpose of supporting the Normandy invasion. The additional weight, wear and tear, meant they weren't expected to last.

Front mounted ancillaries probably wouldn't have lasted long in it's role in the push, and wouldn't have been replaced as the tank itself would have been expected to be replaced beyond the break-out.

I've no documentary evidence for that, but it seems to make sense to me that they'd not add them.
