Believe it or not, this component looks in pretty in good condition in relation to the rest of the rebuild KK
Hi KK, yes I think those gaskets may have been the original 45yr old ones..... I did find a problem though... :o This valve provides cold water for boiler fill if engaged to the right, and hot water from the boiler for the hot water wand, if engaged to the left. The handle shaft on this three way valve has a cam on the end of it that pushes on either of the spring mounted valves, to the left or to the right. After 40+ years of use, it's showing a bit of wear (or corrosion?) on the tip of the cam. Here's a pic of the valve body with the shaft 
This one is a close up showing the cam in the engaged position. (the other valve rod it engages against, which sits horizontally to the right, is not shown) 
And here's some of the cam from different angles showing the wear.. Hopefully my citric acid bath didn't make this any worse, and only removed the scale.. The schematic style pic in my earlier post, with the scale on it looked fine. 
Not sure yet if it's still going to work ok like this or not. I need to put everything back in the valve body and take a look at how well its engaging the ends of the valve rods. Any tips as to what a fix for this might be? Some possible options: 1. Custom make a new cam, cut off the old one and somehow fit the replacement? 2. Add some more material (brass?) to the tip 3. File it off smooth and leave it 4. Custom make an entire new one piece shaft including the cam cheers.
