Alpha & Omega Standards: Part 1

This could also be titled "Way More Than You Ever Cared to Know About Martin's Standards". If you're insomniac, then this is the thread for you!
PART ONE: The "Alpha" Machine.
In this past six months, I stumbled across not one, but two Standards that I felt needed to be at my house. They form "bookends" to my Standard collection. They are my "Alpha" and "Omega" machines.
While not absolutely the very first and very last serial numbers, they embody the attributes one would expect to find on those respective machines. I'll present them here beginning with the "Alpha" machine.
I'm still trying to come up with a name for this one. ("Alphie" comes to mind, but I'm not sure I want to go there.) This is Standard # 873. I spotted this on the UK ebay site. I'm not sure how I managed to get my wife to agree to my buying another machine, but it may be partly due to the confusion of restoring our living room to its 1920s state. ("What's that under there? Why there's another phonograph! How'd that get there?") At any rate, #873 made its journey back to the US this past Summer and ended up at my house in California.
However well the seller packed the machine, the UPS international service managed to wreak its mischief on the poor machine. It was fortunate that the seller had separated the case from the metal parts. Two of the three motor mount screws were sheared off. The brake lever was bent above the bedplate. The halfnut bar was bent. The early single-screw reproducer clips were bent and most distressingly, one of the springs on the early governor (with the brass weights) was bent.
After carefully re-shaping the reproducer clips, the governor spring, the halfnut bar, the brake lever and getting the replacement mount screws from George Vollema, I discovered that the mechanism was jammed. (Hmm.) Pretty much all of the machines I've acquired ended up getting a tear-down and cleaning and this one was no exception. The jam seemed to be where the bull gear of the spring barrel meshes with the gear on the first shaft. I had determined that the best way to clear the jam would be to separate the gear cluster from the spring barrel. Just as I was loosening the last screw of the cluster I happened to think: "what if the spring was shipped with tension on it?" I grabbed hold of the barrel as a precaution. As I separated the cluster, sure enough, I found that the spring still had tension on it. It took me awhile to unwind the spring barrel that way, but at least none of the gears were further damaged. (I still have all of my fingers, too!)
Freed of the bull gear, the gear cluster still wouldn't turn. Upon disassembly, I discovered that the first shaft was bent. (Thanks again, UPS!) The early motors were different than everything made from late 1901 onward, so I knew that this probably wasn't going to be as easy to fix. Fortunately, George came to my rescue once more. He was able to press the original gears on to another shaft.
Newer style vs. early style first shaft with gears.
While all that was taking place up in Michigan, I was preparing the rest of the motor. I have never come up against such a sticky, gooey mechanism as this was. It seemed to have been lubricated with tar. (Maybe the effects of being in an area with lots of coal smoke?)
I'd guess this was the first cleaning it had since 1898. In any case, cleaning involved lots of Lacquer Thinner and scrubbing to get the stickiness off. Even when visibly clean, the bearings in the gear cluster really held onto the goo and the gears wouldn't turn freely. The machine had been advertised as running, but I doubt it could have played a cylinder. Another bath of Lacquer Thinner, some more scrubbing and polishing the bearings finally had their effect.
During the cleaning I found two more things. One was a crack in the motor frame. Possibly due to the rough handling during shipping. However, I did hear that early on, some motors had problem castings and were rejected and re-worked (which may account for some machines with early serial numbers having slightly later attributes). At any rate, it's hard to say who's to blame. The crack seemed pretty stable, so I stuffed a little JB Weld into it as a precaution and moved on.
The other thing I found was a casting mark on the top of the frame. It looks like "2" and "98". Could that be the month and year of the casting? (Inquiring Martins want to know...)
As I said earlier these Squaretop Standard motors were different. They were smaller. Just for comparison, I photographed #873 next to #820428.
As you can see the later motor is quite a bit beefier. In order to squeeze out all of the performance I could of the earlier motor, I took out the mainspring to clean and re-lubricate. The spring itself was in surprisingly good shape. I do have a replacement spring, but elected to re-use the original. I noticed that the casting inside the spring barrel was quite rough. Some of this may have been partially due to slight rust, but was mostly due to not being very well finished at the factory. I'm a little ashamed to admit it, but I very lightly sanded the inside of the barrel so that the spring would have a little less resistance in unwinding. My sin is recorded here.
The test play went surprisingly well. The motor had good power for its size and the cylinder played with a lot less warble than I was prepared for. I borrowed a model C reproducer from another machine for the test play. Although the Automatic reproducer that came with #873 looked OK-ish, it didn't sound good. It will probably need new gaskets and a diaphragm at least.
