The 72nd Brigade catalogue # above is not a typo; for some reason they had two items with the same number.

Consisting of only seven parts, this is a fairly nice conversion effort from this now-defunct company. To create the composite hull, 72nd Brigade spliced together two of Dragon's plastic hulls, an M4A1 and an M4A3. They added some applique armor and some fairly good weld lines, though I think they are a bit overdone. Unlike several other resin companies that have attempted this conversion, 72nd Brigade remembered to change the shape of the overhanging rear armor plate from the M4A3 pattern to the M4 pattern. Unfortunately, it is not entirely correct, because they chose the shape from the late M4 hull, (straight across the bottom) when this vehicle should have the shape of the early M4 hull (not straight across the bottom). I have seen some photos that appear to show the later style (straight across the bottom), but when you look closely, you can see that there was an extension added to the hull in the field. This plate also should be a little more vertical, though the angle isn't horrible.

Two options are provided for the rear plate on the engine deck, one with the oil filler cap and one without, though I don't know that this version ever had this feature. A nice casting mark was added to the upper hull on the front left side. 72nd Brigade also correctly changed the lift handles on the rear engine deck plate to be parallel to the hull sides, a feature that was indicative of the particular tank manufacturing facility that produced these tanks.

So all in all, although not perfect, there is no problem with this set that cannot be easily rectified. So if you happen to see one of these for sale at a model show or on eBay, I'd recommend picking it up.
