M4A1 Sherman medium tank (direct vision) - early - case report

Commanders !!!!
      Taking advantage of the previous case report, let's now describe another Shermie, but with casting hull: the M4A1 Sherman (DV) early

M4A1 (early) DV Finish'em from F Company, 66th Armored Regiment,
2nd Armored Division Operation Husky - Invasion of Sicily - July,1943.
History:
      The M4A1 was the second model to be standardized and actually the first variant to enter in production. The first example being delivered in February 1942, though series deliveries didn't start until March.
M4A1 (very early) under construction. Notice the very early characteristics:
M3 style bogies, direct vision slots, two additional .30 machine in front hull,
the absence of dust cover fitting and of head lamp guards,
the early position of the siren on the left front fender
and the gunner's rotor sight device in the turret.
      Three manufacturers built a total of 6,281 M4A1 (75mm) up to January 1944. In common with the M4, the M4A1 used the Wright R-975 "Whirlwind" radial aircraft engine, and many other mechanical details were similar with the M4 version.

     The major difference between M4A1 and M4 was in the use of a large one-piece casting for the entire upper hull. At the time, these hulls were the largest one-piece armor castings ever made, together with the hulls of M3A1.

      A pistol port was provided for the loader in the turret side, intended for discarding spent shell cases. The hull had direct vision slots and visors in front of the hull hatches, the 3-piece transmission housing, and a rear deck nearly identical in layout to the M4.

       Early M4A1s also had the M3 pattern bogies, and in this form - with full sandshields - the M4A1 first saw combat with the 1st Armoured Division of the British 8th Army at Alamein in October 1942. The British named the M4 the "General Sherman" and "Sherman" was the name which rapidly came to identify all the variants of the M4 family. For the British, the M4A1 was the Sherman I:

       Improvements to the M4A1 followed the pattern set by the M4. One-piece transmission housings, M4 bogies with larger springs and trailing return rollers (heavy duty), M34A1 gun mounts, elimination of direct vision slots, introduction of applique armor and alternate tracks - all made their appearance in the M4A1 by the middle of 1943. However, a number of early production vehicles in virtually the original North African configuration served to the end of hostilities, especially in Italy, where the terrain and nature of fighting did not make such old vehicles as great a liability as in the Northern European campaign.
      Several thousand older Shermans, among them many M4A1s were remanufactured in the United States and England, and upgraded for the European campaign. Applique armor, M34A1 mantlets, and other mechanical and technical improvements were made, and deliveries from U.S. factories and depots. Many more were reworked in England, largely prior to D-Day. With the M4 and M4A3, the M4A1 was one of the most important U.S. service versions of the Sherman and served on all fronts - Europe, Italy and the Pacific.

Kit:
      For this project, I used the Dragon kit M4A1 DV #6404, OOTB
Dragon kit M4A1 DV #6404
      The interior of the box...

booklet
decals and  steel wire in metal
Upper and lower hull

casting surface...
      The triangular reinforcements inside the lower hull contracted, falling from 90 degrees the angle between the floor and the walls ...
the floor is not perpendicular to the side walls...
The fix was simple: cuts in thereinforcements.
This "pushed" the walls out, returning the squareness.
Bingo!!!
Wheels...wheels...and M3 style bogies
Removing the burrs from wheels ..

Done...

Bogies done!!!

I try some techniques to make a very used winter camo. I do some experiments with the hairspray technique to have a heavy chipping but up to now it is not very convincing for me. Fortunately I try on road wheels so I didn't risk to damage my summer camo. I'm also busy with the tracks but I'm not so happy with the track links from AFV Club. So my Tiger will come soon when I will satisfied with the results of the winter camo. Thanks my friend.
