It was Privateer4hire (among others) on the forums here the other day who mentioned that the Macho Machines Sherman was useful for 15mm wargaming. So I picked one up for $2.99 USD at my local Target:
The package contains one diecast tank and a gray plastic display platform.
The turret rotates, but the gun does not elevate.
According to the packaging, another Sherman in desert camo is also available. The other vehicles in this series are an M1A1 Abrams (tan or forest camo) and an M1126 Stryker ICV.
The model measures 27mm from bottom to tread to top of turret hatch, and 55mm from front to back fender. My sample had some abrasion wear on the left side.
For size comparison, here's a picture of the Sherman next to a Soviet T-26...
...and next to a Battlefront Sherman. In the last photo, the base under one of the Shermans exaggerates the difference - the Macho Machines Sherman is roughly 5mm less long (front to back), 1mm less wide, and 2mm less tall.
