WANTED: Gold-plated Sonora needle cups (please click on pictures)

[Zenger]

Greetings! I'm looking for two gold-plated Sonora needle cups for my Invincible. I've included pictures so you can see what they should look like, as they have an atypical shape: For one thing, at least one of them (the outer one) should take a screw in the bottom, and thus has a shape a bit like a bell. I'm not sure what the other one (the center one) should look like, but I don't think it takes a screw (see picture #2), so it could probably be a more conventional shape. Please let me know if you have any for sale, or know of someone who might. Thanks!

Still looking for these. If you have any leads, please let me know!

Still looking!

I am still looking for the middle needle cup, and don't know what it should look like. If you have one but don't wish to sell it (say, if it's in your machine), I would very much appreciate some pictures of it so I can at least know what I should be looking for. Thanks!
