And then a mix of non-sporting guns: military Webley revolvers, an SMLE, and a L1A1. There's more commonwealth stuff, but this is the English/Scottish cohort. There's also the bits for a Bren gun, but that's unlikely to be ever completed as a US-legal semiautomatic.

But hey, I can stop any time I want to. Really. This isn't an addiction.
