In France there are still lots of these (Quincaillerie - my favourite French word)A traditional local ironmongers. 'Nuff said. I miss them, and the stuff we used to be able to get at them.. I think they'd still make a lot of money if done correctly and a traditional one was set up.
Oils, paraffin, Tilley Lamps and the smell of leather too, as well as rope, chains, anchor points, buckles, fastners and the such xx
