You do have a very early Canadian carrier. Mine is CB 8075

There are 3 numbers plus a WD number that can be found on a carrier....If you are very lucky!

The CB 874 just behind the commander's/gunner's seat is the upper hull number.

The lower hull number should be on the angle iron on the outside/bottom of the rear left upper armour plate.

the Serial number and data would have been on a cast plate.

The WD number was painted on the hull.
My understanding is T XXXXXX were britsh built and CT XXXXXX Canadian built.

The CB 875 indicates Canadian Built #875 upper armour plate.
The Lower armour number will not have CB on it

In an ideal world Uhull number and LHull number would be the same but rare.
Serial numbers started at 1000 (so +1000 to hull numbers in ideal world)

Your Carrier was built in either Late 41 or very early 42

Here are some numbers from carriers similar to yours.

UHull # LHull # serial # Date WD #

CB CT 40133

CB 607 1752

CB 3704 3698 1942

6472 Apr 42 T 51176

CB 8075 8105 Aug 42 CT XXXXX

9305 10319 Sept 42

CB 10099 11094 Oct 42 CT113354



My records show 2,927 total carriers built in 1941 and 8,595 built in 1942

It is interesting, your lower rear plate shows some sort of towing attachment mine is for pioneer tools
I hope this helps!
Good Luck!
