Is there anyone reproducing the stanley designed face and the pointer (or have nice orginals for sale) for the steam pressure gauge used in the 740-750? My is in rather bad condition so I would like to replace it.

Any good clock repair shop should be able to disassemble the face and pointer and refinish them.
If your gauge is good and not leaking a gauge shop can celebrate it. Some may even handle the refinishing.
