Re Alex H's post, that is interesting. When my parents bought their place in France (an old farm), the barn had several hundred empty bottles from a failed bar the owners used to have. So we took all that out and the barn is again semi-full of a mix of the useful and the useless: a dozen horse-drawn farm implents (ploughs etc), a winnowing machine last used in ~1978, an outboard motor carefully crated up in 1975 and never taken out of the box since, a blacksmith's drill that has siezed, rusty guttering... then again they have loads of properly-seasoned tibmer, chainsaws, proper tools etc. Main challenge when doing a job is finding the tools and meterials...
Oh forgot to say the neighbour down the road found an old German rifle in the loft (7.92mm Mauser) left over from the war but carefully stored - oiled up but no ammo fortunatley.
