Bigduke6,
Yes, I have been following this thread with great interest and learning a lot from it. I am amazed at how much info there is on STEN rebuilds. Relatively little on the Mk V, but as you say the similarity with the Mk II makes the cross over simple. Two things stand out in that post and others as well: The simplicity and success of the build can be significantly impacted by the type of tools/machines one has available fro the rebuild (Although it still can be done with simple hand tools, welding excepted) Secondly, it appears that an simply equipped work shop could become a manufacturing point for a STEN.
