Why not buy the Autometer made "smiths style"replicas
they have a nice 7 gage set that looks like a smiths
Truly beautiful, reliable but they are mechanical. Some don't like to go mechanical.
Got my set on sale for $425
they are regular $475
Tristate motors
Also suppliers are Kirkhams, and HDR
Here's the link to the gages at HDR scroll down to the 427 s/c set
