Flathead Normal Oil Pressure

Cheers,

Position of the "30" is in the centre.

Style of the 30 and 80 are drawn from the 1940 100Mph speedo.

Hi Tony,

You beat me to it! Just remembered I had a photo of an earlier speedo I sold which I was going to use for the style of numerals.

Thanks for that photo. Better than mine and should be easy to make a similar looking oil pressure gauge face in keeping with the period.

My misunderstanding was a need to convert the later 0-80 psi gauge to the earlier 0-50 psi. I guess there still is a need in view of the availability of the later gauges if people still run the 50 psi pumps.

Note: I have attached 0-80 psi gauge face to resemble an earlier 0-50 psi face. Think I got the "3" and "8" OK from the speedo photos. Not sure if the top of the "8" has some fill in but it can easily be changed. I darkened it slightly over previously posted versions too.
I found by scaling this photo to 25% before printing, it matches my later 0-80 gauge face perfectly.

Cheers,
