Thompson SMG

David had a good point. Look at an official Pam for the Thompson. I just so happen to have one on my shelf! Usually all my manuals are displayed with my field equipment but sadly I do not have a Thompson to display with my manual. Maybe one day?
In the manual it lists a 20 round and 50 round magazine available. There is no mention of a 30 round magazine!

That is a nice early edition of the Thompson SAT.

That is not too surprising. Your manual is dated 1940, and per Wikipedia:

The 30-round box was approved as the new standard in December 1941 to replace the "XX" and "L" magazines.

While the Small Arms Training wartime series of manuals are good primary reference sources on how to hold, load, aim, fire and clean the small arms being employed by British forces, they really do not delve too deeply into the minutia of the weapons. I have a pretty good collection of SATs and have checked through the later editions for the Thompson and Machine Carbine manuals and did not see any reference to 30-round magazines.

Another source that would record a change in Thompson magazines would be the RCEME publications or even the Quartermaster entries in the wartime Divisional and Corps files.

I am still looking to see if I can locate a wartime photograph of a Canadian using a 30-round Thompson magazine.

These could be:

These are troops of the 1st Special Service Force, a joint US-Canadian unit. But proving that the men holding Thompsons with 30-round magazines are Canadians may be difficult.

The 1SSF were given, but finding a Canadian using a 30-round Thompson magazine in I Canadian Corps is the challenge.

Hi Jakko/Ed: Looking closely at the photos, you can see 30 round magazines but this is MY observance and I stand to be corrected: The large group photo shows about 4 soldiers carrying Thompsons. 2 soldiers in the upper centre left definitely have 2 units with 30 round mags. Centre right beside the Browing 1919 is definitley a 30 round mag.
In the other photo, one soldier rests his arm on an ammo belt/pouches which look to be 30 round mags.
Thats may 2 cents on these photos. Thanks for the posting.

Yes you are correct as there are indeed 3-round Thompson magazines in the two photographs and there is no disputing that 1SSF, a composite American special forces unit containing Canadians used 30-round magazines. But to answer your initial question did Commonwealth nations use the 30-round magazine then in the case of Canada, you need to find evidence, either a photograph or wartime document from Canadian sources to prove that particular magazine was used. If I were searching out the answer, then I would focus the hunt on I Canadian Corps as they fought in Italy where the Thompson was used.
