Made one yesterday out of some modern plumbing fittings.
25mm brass threaded-barbed connector,
25mm galvanized end cap,
three copper sump washers,
a rubber 0-ring,
bit of stainless steel filter mesh cut into a circle.
Drilled large hole in top of end cap, filed out leaving a few mm flange on edges, dropped in an o-ring slightly larger than hole, pushed in piece of mesh filter, dropped in three copper sump washers, screwed tight onto barbed connector, all done!
Can be easily screwed apart for cleaning etc. Looks and functions pretty much the same as original. Will do until the real thing can be found. :-)
