About 15+ years ago I was in a local hardware supplier and they were just going totally metric.(Shelf space and declining imperial sales) So I bought the complete remaing Imperial stock. I've nearly run out of stuff now but I had a good run. Regret there was no CEI in it.

30 odd years ago, our stores had a clear out, the majority of UNF/C, BSF/W, BA. UN, bushes, pop rivets, bearings etc were deemed as not required for future use. (modern railway brake systems dont need 200 UNF nuts or bolts only metric and a few BSF). Our machine stores didnt require many obscure standard and purpose made taps and dies.
working on nights involved a great deal of skip diving. at the time, the two boys were finished with baby milk, the garage was full of soon to be filled tins.
unfortunately due to a house move many fastners were sold, a mini restock a few years later ended going to a rally driving mate to look after while we moved house again. To this date, Ive never collected them, probably skipped by now.
still have a good supply of phos bronze bushes, roller bearings and pop rivits as well as standard metric fastners BUT I do still have many taps and dies.
