Hi,
I have an old (1950's I think) sprayer much like this one:
https://solosprayers.co.uk/No-27-Sol...Garden-Sprayer

When I try to use it, water just leaks out of where the two pump pieces
join. I'm assuming there is a washer/seal/gasket missing but I just
can't work it out.
If anyone has any form of diagram or exploded view, that'd be great to
see what's missing.
Ta.
