modified M22, Motion? Questions

[goinforbroke]

I was offered a complete M22 setup from a friend at a fair price. He said the transmission came out of a Motion Camaro. It is odd, painted red,white and blue with a metal B M tag on the case. He said it was built by B&M transmissions and the synchros were modified to shift without a clutch. Is there any way I can tell if it's from a BM car? Were their transmissions modified or was this possibly done by B&M trans? Any info would be greatly appreciated. I would like to put this behind a mild 454 in my 72 Nova SS. Thanks!!!
