Glad they were still making the valve sets in the late 30s!

I don't have a better suggestion for the 4th valve circuit, but somehow it doesn't match the aesthetic of the others?

Indeed there is a weird perverseness in me what particularly likes the earlier variant on the 3rd valve circuit that sticks beyond and under the wrap. But that is protected by a helicon bell that don't come off, whereas sousas' bells do (so i think i understand some design trade offs involved?)

Sorry i forgot your birthday!

And it took me this long to remember the notice at the bottom of the index...

PS I still like Keefers.
