At a minimum, here in Canadaicon, a collector MUST have an Inglis mk1, a Mk1(M), and a MkII. Then any oddities that surface like the CH serialized Bren, and the transitional mk1 to mk1M DD Brens also have to be added to the collection. Now I read about these sterile Brens, so I will have to make space for one more.

One could also get duplicates of some of the marks for the different buttplates on the mk2, and for the different length of cones on the mk1. Also, the early mk1 machine work is nice to have as well. But adding these might be getting obsessive.

I never got into the foreign brens or the CZ guns....not common here and lacking the Cdn connection.
