MTH used Hobby Master 1/48 Sherman tanks in the past, this run they used Solido Shermans which they said were 1/43. If you look at Ebay's listing of die cast Sherman tanks you will find the in the 1/50th scale. Does not matter 1/50 is real close to 1/48. The Solido ambulances are 1/43. Use eBay as a source you can find many Solido items there.
Paul,
During WW II Sherman 76mm cannons had muzzle breaks as well as no muzzle break. I have a book "Sherman Tank in Action" that shows both. Again this run of MTH flatcars with Sherman tanks were Solido.
D500,
The Sherman tank was named after General William Tecumseh Sherman the same guy who burned Atlanta and marched to the sea to capture Savanah. Sorry to bring that up.
