I am looking for a M4A3 76(w) Battle of the Bulge Sherman in Canada and I am also looking for infomation

You can purchase the Dragon M4A3(76) at many of the sponsor links on the left. I don't think any are Canadian but that shouldn't make much of a difference with any of the sites in North America.

I think you need to be much more specific about the info you need. Some people have taken years reading, researching and photographing. It would be difficult to answer non-specific questions
