Re: I paid too much, I'm sure
Pretty cool. I've been watching that (and the cage mount) on eBay. Looks like the seller has/had multiples of these.
$1.95 in 1958 has the same buying power as about $17 today. So factoring for ~62 years of preservation of a relatively low production accessory part for an early engine, still in mint condition. I'd say $40 isn't bad, just a little over double the original value, especially if you are happy with it. As close to going back to the late 50s and ordering it out of a catalog as you can get.
Are you going to keep it NIP or open it and use it?

40 $ is a normal price for this rare item.

I don't understand, what switches the speeds?

I guess the high speed valve fuel line was clipped by a timer to switch to the low speed that was open more by some turns to feed rich mixture?

Re: I paid too much, I'm sure
So if I understand it correctly, the second fuel line can be opened to flood the engine, thus running slower, and pinched closed to lean it out by operating on the high-speed NVA only, is that correct? I guess you'd set your main needle for high speed with the low speed needle closed, then open the low speed needle until it reduces the speed to where you want. Then pinching the line has the same effect as closing the needle. Is that about right? Can't imagine running low speed would be so good for the fuel economy though

I'm thinking that it would have been a huge advantage primarily for final-approach/landing; being that you could now control when and where you want to land, without it being dead-stick.
