If you have Smiths, I'd stay with Smiths. The Kirkham gauges are pretty but I'd have them only as a matching set.

I just took the keys to my ERA, but I'll be ordering the Smiths voltmeter on Monday.

Note that Nisonger also has a Smiths voltmeter for a later era, with colored bars. It would look awful in a Cobra dash, IMVHO.

That's a good price from Gauge Guys. Nisonger quoted me $85 plus shipping.
