Lanchester Mk1 SMG

Thanks Peter. That’s how I thought it worked.

No spring to return the tripping lever!! That’s interesting. So once the breech block cycled in automatic and lifted the tripping lever there was nothing to reposition it?

Without a spring to reposition the tripping lever it looks like the disconnector would hit the side of the trigger bar extension when the selector is moved back to repetition. That’s if the disconnector is still held by the selector after the tripping lever has is raised by the breech block cycling.

Yes, now I see why the mechanism was removed.

As this will be a closed bolt, semi-auto only, I think a similar arrangement would work. There would be no disconnector, just a one piece tripping lever. I would like to use the breech block below, Mk4 Sterling modified to semi-auto Mk6 configuration. This means moving the sear forward for the firing pin, and a longer tripping lever. An arrangement like the STEN might be more suitable though.



I would like to keep the appearance as close to the original as possible. Maybe have the safety where the selector was on the Mk1.

There’s no doubt the STEN and Sterling are superior in many ways. I am just looking to have some little bits of history that I can take out and shoot on Sunday afternoons.

BTW, Your STEN book is very good too. Any chance of Bren book? I got a Mk2 parts kit yesterday. It will be my next project after the Lanchester.
