Ford Inlet Manifold part No. prefix C29SR question

[Lynn Eades]

Hi guys, for those that like a quiz (and I want to know) I was just wondering what it came off specifically.

C=Canada
2=1942 production
9= 95 hp
S= Special Veh????????
R= Rear engined ???????

The manifold has the supports for the very big 12 volt generator (I have one)
It has 6 mounting bolt holes in the carb mounting face this allows the 2 barrel to be reversed on the mount.
(If the carb had turned around to fit the genny, then why make it so it fits the carb the other way as well?)
Logic dictates there was a second application for this manifold????
It has a separate removeable bolt instead of a stud at the generator mount and has a toothed dog and tube bolt to take the U.C. fan extention.
Is this from an Indian Carrier, or an Armoured car?

I have a parts book for the 1941 rear engined CMP 4x4 and they are the following models;
CO11QR, C191QR, and (1942) C291QR.
