'67 What 4spd do I have??

I just bought a '67 with a 350 4spd.I am unsure what transmission I have?The shift pattern has reverse down and to the left pattern???What did this come from??Any clues?Will any numbers on the trans. help?Where can I look these numbers up??Thanks.

If this is a Saginaw ,did these come in camaros?Is this the normal shift pattern for all saginaws?

I dont beleive saginaw trannys came in any 67,68,69 camaro. Although I could be wrong. The defining difference between Muncie and saginaw (visually) were the housings. Muncie's were aluminum cases, saginaws cast iron. Muncies came in the M20 wide ratio, M21 close ration (spherical gears) amd the M22 close ratio with spur type gears. On the Muncies reverse was up and to the left.
