I also wanted to use both turrets.
I'm just as stubborn as cptjake, but to lazy to convert the turret to fit, so I just used my Rubicon Models M4A3 Sherman hull. Depending on which turret to use, I can have either the M4A3 or M36B1.
Some notes to make:1) A lot of combat photos and footage I have see show the tank without the muzzle break. Removing the muzzle break was very easy, and scratch building the collar ring wasn't that difficult. However, I even didn't bother with the fine threading at the end of the barrel in front of the collar ring.
2) The kit does not include crew. The crew figures are plastic and converted from various other figures from Rubicon Models plastic kits.
3) I used a brass pin so the HMG actually swivels. I didn't have to do that, but it was pretty easy, so why not? Also, it can be removed for easier storage and transportation to games. I use these models for tabletop gaming.
M10 and a M36:I do have another M10 kit, and when I get around to putting that one together, I will do the same thing that cptjake did. Thanks for the good idea cptjake.
