Thanks for the help Henry.
We had a good time in Montreal but it was a tad cold. At least it wasn't snowing like it was at home. Most of the historical things were closed. The forts mostly shut down in Oct. or Nov.
We did go to the Stewart Museum. Only part of it was open but we did get to see some things. 4 or 5 flint muskets and trade guns, a wheelock, and flint pistols. There were 3 of the scottish all metal flint pistols, one of which had a very large bore, more than an inch. There was a pistol-like contraption for testing powder.
One other oddity was massive gun intended to be mounted since you wouldn't be able to hold. It had two legs that supported it. The stock was probably 3-4" thick and wide and a large long barrel. Appeared to be a matchlock.
I may make the trip back up that way next summer and see more.
