The diverter you show is used by Newport Brass and others. It is made by "American Faucet and Coatings" the parent company of Sigma Faucet. Their part # for this diverter is 18.30.113. That diverter was designed to use a tension washer you don't show and would explain why pushing downward helps...

Can you post some photos of what you are working with? Their are different Andre collections and Andre faucets.

I've looked this over and over. The only thing I can see is the original transfer cartridge is missing the lower o-ring seal. Did you ever remove it?

What an awesome find. I've seen lots of pre-war Crane valves but this is one I've never seen. Thanks for sharing.

Being that the original problem was the valve dripping I would replace the seats and springs and reassemble.

The one you removed looks to be from a Crane drain. You will need to confirm measuring the diameter and the threads per inch. Crane is 1.8"/14 T.P.I. Look at the chart to confirm. All the sizes shown have been used in tub drains. https://www.watcomfg.com/watco/PartsAccessories/BushingsSheet.pdf

What you see is the A954440-0070A. Any of their Flash trims will work. You will not be able to use the cartridge that comes with it.

This looks like the faucet you have. The H/C indexes should pop out to access the screws. https://www.homerises.com/centerset-bathroom-faucet-cross-handle-gooseneck-antique-brass-p-hois50208_5662.html

It sounds like bad cartridges. The chrome plungers on the bottom of the cartridge control the temperature. When you first turn on the valve the cold plumger begins to open. As you continue to turn the handle the hot plunger opens and the cold retracts. You can test this with the cartridge...

The bonnet nut is metal (Zinc).

If you can remove the handle you can see the model you have. The 3 screw is the R111 shown above. The 4 screw is Ultra Mix with a brass stem.
