Excellent point about the Iberian Pen, also Spain has an amazing history of gun making especially up north.The propensity of Ruby pistols from WW1 is just the Tip of the Iceberg.
If I had the joy of going to Spain to snatch up some weapons. There are several I would grab just just because they so hardcore.
ASTRA 903
Because what good is this world without Machine pistols!!!! Especially i you can attach a stock that is also a holster!!!!!!!!!!!!I know its 7.63 Mauser but you could be risky and shoot 7.62x25 Tokarev in it!!! ( it's Almost Identical cartridge, but its way more powerful!!!!!) Thankfully many where converted to 9x19mm(9mm luger) and some for 9mm LARGO (9x23) which can use COLT .38 super (but again its much more powerful)

STAR Z62-Z63
These are such mean looking SMG's!!! the 63 in 9mm and the the 62 in the more powerful 9mm LARGO. Rarely seen other than in Spain (maybe Africa)
I have always wanted one of these guns. Looks like a cross between a Sterling and TEC-9.

Id probably go definitely for some The CETME Model C and maybe some old CETME Modelo B's for even a little more flair. (they look really tough with the sheet metal fore end) But they CETME is a really rugged Battle rifle! The sights are a not as good as the G3 But they are easy to use. Magazines are very sturdy and I can really see it as a Twilight 2000 firearm.

And I get tons and tons of FR-8's nice lightweight Mauser converted to 7.62NATO be a great gun for men on horseback or bicycles, has a very solid wood stock and uses CETME bayonet for those moments when you got to beat or stab someone to death.
I can see Spanish guns on British Soil I rather like the idea of this. Could be used for a game in itself!!!
