Okay, here is the latest, after soaking the screws with PB Blaster and using visegrip on a stubby fat slotted screwdriver, the brass cover came off.... unfortunately, the repair kit the plumbing supply house said was for this faucet doesn't look like it will suffice.... it may be the wrong kit.... you can see the chrome hexagonal cover in the one photo.....
Any guidance anyone?????
Addendum: I am still not sure from the diagram as to what the difference is between a B201 and a B202. As stated above, the repair kit was improper.
Here is a link to the schematic for the B 201 and B202.
American Standard diagrams start on the tenth page of pdf
R1400 is on the 13th page
B201/B202 is on the 14th page
Unfortunately the pdf copy is not very clear as to the assembly. I have emailed American Standard directly to ask for a schematic from their archives, and their response is that they don't keep anything past 15 years....
I did manage to cull some interesting tidbits from some archival sites in my webcrawling and here is a quote:
"Standard Factories will supply your Home with health and comfort giving plumbing fixtures of first quality, just as they have supplied millions of other American homes. Since 1900 they have produced more than twenty-eight million ''Standard" Plumbing Fixtures.
You can equip your home entirely with Standard Plumbing Fixtures and so center the responsibility for the whole installation on one reliable manufacturer. ''Standard" Factories not only make every type of plumbing fixture and accessory the public requires, but also make more of each kind than the factories of any other manufacturer in the world. These one hundred and seventy-three and one half acres of buildings are not merely factories of mechanical industry, but they are peopled with ten thousand interested workers, anxious to keep "Standard" Plumbing Fixtures unsurpassed in quality. Most of these employees have been with this Company many years and own stock in it.
Re-Nu bronze sleeve:
Standard Re-Nu Valves have internal bronze sleeves which, with the stems, comprise the only parts subject to wear. These when worn can be replaced at a nominal cost.
RE-NU Feature for Standard Faucets and Valves: The removable barrel or working unit containing the seat and threads embodies a principle of construction that makes for the almost perpetual life of the fitting.
Re-NU line an integral part of the removable barrel which is made of high grade bronze metal. This permits easy replacement of these parts at small expense, making the Re-NU Faucet in operation as good as new.
In the "Standard" General Catalogue are many Showers, from the very simple to the many varied, elaborate Showers designed for all preferences and conditions. The real essentials of the finest Showers are the shower head and mixing valve. Water is tempered by the K 100 Mixing Valve which is safe, dependable and the parts few and accessible. Maximum high temperature of water to be delivered can be set by a small adjusting screw, provided the cold supply is not entirely shut off. This feature is a safeguard against scalding and insures proper mixture. Volume Control in shower head regulates the force without changing the mixture."
The RE-NU feature is a separate renewable barrel which slips into the valve or faucet body. The ground joint principle is employed in sealing the Re-Nu barrel to the body of the fitting. The threads engaging the stem and the seat are cast into the Re-Nu barrel, and the wear caused by opening and closing the valve will occur on these parts.
After many emails and websites, I have the following to report:

Needless to say I have placed my order for parts with Chicago Faucet Shoppe.
At this point I have closed it back up and am waiting, but I do want to note that the two sleeves have become frozen and will require some soaking with PB Blaster to free them up so I can replace the washers at the back of them. The two plungers came out readily from them, the hot plunger is on the left in the photo below and has a regulating screw in it - I have not touched the regulating screw so I am presuming that upon reassembly my mix of hot to cold should be as ideal as it was before.... the cold plunger is on the right side. If anyone has a spare of that particular cold plunger there is another forum member looking for that part - Bob Cleveland. Both Bob and Walter have provided advice as to freeing up the sleeves.
I will no doubt have more questions on re-assembly when the parts do arrive as I don't have any traces of the prior renewable pieces to just pop out and replace -- the prior repair was done by a silicone happy person who didn't bother to consider using parts I suppose. Only good thing is that as you can see in the photo, that person used a whole lot of silicone caulking in the wall around the outside of the faucet body, so when the cover plate came off absolutely no residual water infiltrated the wall..... while I am waiting for parts I will clean that out and fill it up again with silicone....
I also need to consider what to do about the conditioning of the water supply so I can extend the life of my plumbing.... anyone have any ideas?
