Yes, I could not find a cord, and there doesn't seem to be much available info about those. I'm curious about how it is wired.
I was able to purchase a sight glass assembly and filler cap. On second thought, I don't think this model came with a pressure gauge, as it looks like the boiler only has 4 top ports (pressure relief, whistle, steam pipe, and filler cap?). Pictures of similar engines with a pressure gauge show those have 5 top ports on the boiler.
Happy Steaming!
