If they insure old farm tractors and old restored Semi's etc etc, then there is liability insurance for the carrier.
Number one, I would stay away from calling it a "bren gun carrier"! Call it as it is ,a Universal Carrier. Guns are bad, this is Canada you know, so don't use the word to some urban clerk who goes home and watches all those stupid murder shows, CSI and America's most wanted, etc., ad naseum , shows.
It is an unarmed tower/hauler. Like a tracked tractor. No sir it is quite small only 8000lbs same weight as a 3/4 pickup and much lighter than an agricultural tractor, in fact many were turned in to farm tractors in the 50's. Forget the Mark twos and PIAT mounting points etc , he/she doesn't care and may become TOO interested in your carrier. Its just a plain old tractorish vehicle that you'd like to take to shows.
I have had trouble licensing trailers and other items when I was too detailed or honest, for example I have a company made trailer that was modified by another certified trailer company but do you think I could get it licensed when I told them that? No way, so I go to another office (after a chat with a friend) and say "I have a homebuilt trailer, make it number 0001" and I have a trailer license in about 8 minutes.
for what it is worth.
