Sten barrel line drawing.

[Flying10uk]

There was a thread, some time ago, where someone had a very early U.K. spec deactivated MK2 Sten that had a removable barrel, like a few of the early spec deac Brens. I can't remember who it was who had it but if they've still got it perhaps they can take some measurements for you?

This may have been it? http://www.milsurps.com/showthread.php?t=56537
