I went to NAPA to order an O-ring and oil seal for the pump. I think my local NAPA is under new management. I was told that the O-ring I needed had to be shipped in from their Texas warehouse and that shipping would cost $10. Oh yeah, and on top of that, since the O-rings come in boxes of 10 I'd have to pay for a box. Told 'em I'd think about it (didn't take much thinking).

Jumped on the Internet and found a local distributor of SKF oil seals. Called them up and ordered 2 seals. They had it for me the next morning, their office is literally 3 minutes from my home, and I got 2 seals for less than NAPA was charging for 1. I'm taking the pump housing in tomorrow to see what they can do for an O-ring (I have to wait for the paint to dry in a very cool garage).

I came home and installed the new seal. I then partially disassembled one of the window cylinders. I'm pretty sure it's the one from the driver door. I was very pleasantly surprised to find it in much better shape than expected. The piston is aluminum, the cylinder is steel. The rubber gasket/seal was like new and will provide an excellent example if I need to replace others. I was afraid that the interior of the cylinder would be pitted beyond use but there is only light pitting near the bottom of the cylinder and shouldn't affect operation.

I compared some of the cylinders I have and noted two different methods of construction. I wonder if the cylinders are from different car makes, or a running Packard change sometime during 1941-1942?

Tomorrow: Remove the passenger door panels, figure out how to get to the divider window mechanism and remove the rest (4) of the window cylinders. I'm keeping my fingers crossed that they will be as good as the one I've already inspected. I will then have to see what to do for 'dust covers' on the top of the cylinders since there is very little left of the original rubber boot. I'm not surprised that the rubber boots are shot when you consider that the Packard Service Bulletin was advising the availability of replacement boots in 1942 after they had been in service only since the 1941 model year.
