A neighbour of ours has a big collection of historic rifles, mostly live but a few de-act's, stuff from Martini-Henries to Mosin-Nagants, Lee Enfields and so on, all legally registered. I bumped into him a couple of weekends ago and he was just off to collect the third big safe from a jewellers that had gone out of business. He reckoned they weighed between one and two tons each and they were moving them out with a pallet truck, a come-along and lots of sweat. Once he got them home on his car trailer then as he's a farmer he just picked them up with his telehandler. They had to wait a week for the second couple as the shop owners had to demolish a couple of stud walls to get a better route out of the building as the floor started to crack when they attempted to move them so a few props down in the cellar and some sheets of ply to spread the load (rather him than me!) He basically got them for free if he removed them, they are fairly old but have both key and combination locks and will be resistant to all but the most determined of burglars. Might be worth looking around for something similar. We have a small antique safe that we use more as a piece of furniture but even that is good enough to resist most of todays crackhead thieves.
