Asbjørn: the carrier is a NO-2 MKII* as manufactured at Ford Canada, in Windsor, Ontario for a British contract, SM 1447. As such, the "T" War Department number on the exterior is likely correct.
It appears you have a standard generator, generator cut-out, and "diver's helmet" style distributor, correct for the C81 engine installed in the series C31UCW carrier. Hopefully the after market coil is 6V?
Very nice original engine tag!
A swell looking MKII* C31UCW.
BTW: Serial number 29778 ... amazing! This partially clarifies/supports how the production numbers may have related to either the serial number or hull number.
As the serial number is over the Milestone final production number of 28988, perhaps the CB upper hull number(s) like 28739 is the factory guideline?
If you can please tell me the lower hull number off the angle iron supporting the rear vertical armour, bottom left hand side, that would be excellent.
About the original Ford style coil:
You can go back to an original coil, rebuilt with modern components and a three year guarantee for about $75.00 USD plus shipping. You would send the original coil to Skip Haney, in Punta Gorda, Florida, USA. If you do not have one, and want one, I will give you one as a donation to the museum.
