Wow...I missed that other thread....so the Magnatex mystery seems to have been sorted out and the BENNETT style can reinforcement seems to be seen on that Magnatex example. Over here we do see a lot of the regular British cans but I have never seen a Magnatex one around here. Being on the West Coast means a lot of what has been shipped back to the US like M201 stuff and British gear isn't as prevalent as it is on the East Coast from what I have seen.
