Steve Walker pretended :
I've wiped one or two lead joints (although the only lead we have left now is
the supply to the house), but I am definitely not a plumber - I don't even
know where my moleskin has gone.

Me too, I used to love wiping joints and gained quite a good reputation
for the ability. By then it had become an almost obsolete skill. I last
needed to do one in this house, before it had a full refurbed back in
the early 80's.
