I don't, but here is a photo that shows a bit more of the headstock. I copied the tag from a higher resolution copy of the same photo. It almost illegible, but there is a squared off "S" in the upper left and it looks like entries for model number and serial number are below it.

installing the fulcrum for the equalizer to the lead truck? Or just playing hide and go seek under the cylinder block?

The position of the eccentric repair bushing shows how much had to be bored and bushed to correct the out-of-round condition due to wear.

Getting closer.

The photo shows the historic Alaska Railroad Anchorage depot a couple of days ago. During a normal year, we would have just finished staffing a 557 booth in the depot during the nine-day-long Fur Rendezvous winter carnival. This year we missed visiting several thousand people during the annual "Great Alaskan Train Show" this year.

Where but Alaska can you find a mixed train?

The trial fitting of the driver journal boxes means that the re-wheeling of 557 is coming soon!

I was raised in Fairbanks, and hope to be coming in 2022 for a long visit, depending on the state of travel through Canada, at the time. I have been following your post with keen interest. :)

Lacking universal joints needed to add additional valves to the turret on 557 for an additional generator, I created a prototype sized replica Nathan #1 universal joint and 3" diameter Nathan #1 valve handle in silicon bronze last week. The U-joint is 3" long.

Prototype drawings were courtesy of the Steamtown National Historic Site archives. Within hours of my request they were able to supply both the parts identification drawing used in a catalog and the shop drawing with detailed design and machining dimensions.

Since I had already done the work to create the 1:1 digital 3D model, I decided to see if I could reduce them in size for use in a model. I printed the parts at 1/4 and 1/8 scale. The printed parts at 1/8 scale are probably too small to machine (and almost too small to see for my tired old eyes), but 1/4 scale looks practical and I'll give them a go next time I do some casting.
