Just some random thoughts on this piece of artillery. It was also known as the pack howitzer as the whole gun could be broken down into small sections capable of being carried by a mule pack train in the mountains.
Some people called it the spaghetti gun as its parts flopped all over the place, kind of rattling piss fit idea.
There were two Britains die cast toys of this. One has trails that are not flexible at all joints the other one has all joints flexible.
The Canadian Forces used them but were withdrawn a few years ago, a few are monuments in front of Legion branches.
None in civvy hands in Canada that I know of, they were towed by the Chev 5/4 ton trucks.
Seemed to have dissapeared around the time of the bisbandment of the Airborne after Somalia.
