Years ago my granddad told me you could buy the little rubber tube that sits over a bicycle tyre valve separately, rather than buying a whole new valve. Of course I was told they didn't have them since back in the day (i suspect you can probably buy them again now with all the Greta stuff happening now)
Another time I tried to buy a blade for a really long bushman saw and I was told to "go for an easier life"
If only I could record it covertly I'd go into the local co op and ask some young lad/wan who is just after starting for a well chain
"Ya know the chain for lifting the wooden bucket out of the well?"
"You don't? ahh you must be using a rope at your gaff so. An auld hemp rope will do if you have one"
