Being inspired by this thread, I am having a machine shop make me some of the fittings needed. I'd asked Richard Lage if he was interested in making them and doing the mag modifications, but he's too busy with other fun projects!
After measuring multiple drums and coffins and my Max31 and Max31A uppers, I decided I'd post my drawing here in case anyone wants to make their own... or I can have a bunch of extras made if there's interest... probably at around $6-$7 each (the machine shop says the parts being small and more difficult to handle makes the cost higher) in small quantity. I'm having them made in unfinished mild steel so they can easily be tweaked/fitted, and cold blued or Duracoated when I refinish my dozen or so old Sten mags.
