Can anyone enlighten me about....
 

The guns shown in these two photos of my Gr-Gr Uncle?

What type are they, and where would thay have been used??

The gun is a Bofors 40mm anti aircraft gun. These were used pretty much by everyone and almost everywhere. Still are today in some navy orgs. The guns were assembled by different manufacturers under licence. Here in Canada Otis Fensom elevator co (OFEC) made ours.

I was told last year that 40mm ammo was still one of Bofors best sellers.

Thankyou for the info:

I have also recieved this photo, from the markings I believe he was deployed with:

C Troop
25th L.A.A (Light Anti-Aircraft) Battery
Royal Canadian Artillery

I believe the gun pictured is the same as in my two original photos.

My research tells me the 25th LAA Bty was a home defence unit, part of the 6th Cdn Infanry Div. Now part of the Div was sent to Kiska (not the 25th), but other than that am I correct to assume that he would have not seen overseas action, unless he left the 25th?

Thanks for your help...
