I'll refer to the book again Vinnie. But, basically, you've got it! From my memory of these things now, there is no spring that operates on the actual tripping lever (P9, Item 8) but when the change lever is set to 'A' , the hinged disconnector (item 10) is rotated out of harms way and thereafter, its position is a bit academic. But when the change lever is set to R, the disconnector (10) is allowed to spring inwards and sits underneath the squared tail of the trigger bar extension (2). Trigger pressed and all that........ now as the lever (8) is tripped by the breech block it tips downwards, lifting the rear and the disconnector (10) lifts the extension (2). When the extension (2) reasserts itself, it is this, acting under the influence of the spring (3) that moves the tripping lever back into position.

Obviously that is a very quick and brief summary that would earn me 1/10 if this was being marked by one of those mean, tight fisted trade test examiners! And many other things are working simultaneously too.

You can see/understand why this mechanism was doomed from the start and just why the Sten gun and later self contained Sterling SMG's were far, far superior. I have to say that I acquired three of these as de-wats in the UKicon and the quality of the workmanship was dire. Can anyone decipher the arabic writing stamped under the brass magazine housing in one of the previous photographs?

Thanks also for your kind comments about the book.

Has anyone else out there in Forum-land got one/any of these beasts? I remember seeing them advertised for regular sale in the US, in some old, early 60's US shooting magazines. They can't ALL have got the chop? Or do they now all live under floor boards?
