There is a Company in Munich that produces single fire Versions of several machine guns and machine pistols, but they don't have a Bren in the line up. If they could get hold of a truckload they would probably be offering it. I know they have Stens and MG42 Units for sale that have been registered as Sport rifles in Germanyicon, so they should be acceptable in other EU countries, but I don't have the 4200 Euros they are asking for them. I think I saw the Sten for 850 Euros.
