Hi guys, sorry for the VERY late reply. I've recently redone the Lewis a bit. Can't sadly take her to cons anymore since I have a crack in the cooling part. But I'll post an update and some pics as soon as I get the chance.
That's cool as hell, and a super clean print [read: suspect heaps of sanding has gone into this, yeah?]
I've binged the series, but I only vaguely remember the Lewis guns being used (and from a prop design PoV for the show, I wonder why they opted for the aircraft version of the gun).
