Both of your new acquisitions are way kewl!
That 'Time' pump plate would look great on a clockface. I don't know if that would be correct for the vintage of the plate - but the clockface and the face on the sign would look stunning together. And I'm sure you could have some fun designing a unique paint scheme with the red, white and blue colors.
I have seen version of the 'RPM' sign before - but never in that condition and as a flange sign. Major score on that one.
