Hey Paul, I was just over at your site, wandering through the SMG section and I noticed that for the Swedish M/45 the select-fire model made for the Swedish police is labelled as the M/45E. It should be listed as M/45BE.
There was also a model of the BE adapted to fire blanks only to launch tear gas grenades, the M/45BET.
There's a brief mention of it at the Historical Firearms website, the info accompanies a very interesting photo of Swedish police body armour. The head protection shown could be an interesting sight coming at you through smoke or fog!
