Looking good, liking the copper coil a great deal! As for the acquisition of replica (from water pistols up to blank firers) there has been a recent tightening of the laws around the ownership of replica firearms her in the UK- so much so, that you can't buy 'realistic' looking toy water pistols and cap guns anymore, I know, I keep on looking for them, and I can't even find Nerf guns in mu local Toys'Я'Us! Pity, as all I want is the hilt to build upon.
I tried Toys R Us as well; nothing to be had gun-wise except for a few cowboy silver six-shooters, pirate flintlocks, and a Star Wars imperial blaster/silly string gun.
Apparently Sky High Kites sell Nerf Guns, but I haven't ordered from them as yet, and as such, can't comment on their honesty (or lack of?)
