If in the Kingston area I would highly recommend checking out the PWOR museum in the Armoury on Montreal Street. They have an excellant collection of military weapons and kit. Check their website for times and details.
gun show but with decent stuff. Not the usual 22 from the 50's and things like that. More tactical and relavent to todays world. I am sure the base would happy to have something like this.
There is going to be a good sized gun show in Napanee in June btw.
