Montreal Gun Show Acquisitions

Went to a Gun and Militira show in Montreal yesterday and picked these up for decent price. Can any one tell me what the trade badge on the Battledress blouse is?

I can't see the badge clearly, but it looks like anti-tank group 2.

I'll take a closer pic of it and post it.

Hi, it is an anti-tank gunner gp 2 trade badge.

Are there any reference books or sites for canadian army trade badges and insignia?

There was a book published a few years ago on Canadian army trade badges, SKILL AT ARMS by Tom Bennett. But it is out of print and hard to find. Maybe try Abe Books.
There are lots of books around on Canadian insignia, but some are hard to find. Depends on what you are looking for. A good list can be found here: [You must be registered and logged in to see this link.]
