The crew figures are from GHQ, and I suspect they're going to be too tall for the guns (as GHQ infantry are wont to be). I'd rather be using Heroics & Ros figures really, in spite of the lower level of detail, but they're taking a very long time about fulfilling orders these days and I don't want to wait another six weeks to get the bases done.
Something I realised when I was gluing the guns down is that there's no actual gunner. He should be sitting on the seat on the left of the gun, crouched over the sights — I think I might have to revisit the file and add one.
I'm using 25x25mm bases (cut down from old credit cards and the like), which would make the standard 8-man crew a bit crowded. However, the official "low establishment" crew was only four, so I've got a bit of leeway.
Couple of days later
Considering the size of games we're usually playing, it's unlikely I'll ever need to field a whole twelve-gun battery, but if I need to, I now can. There's a comfort in that.
