My very cool sister scored these sweet gauges and gave them to me for Christmas!

  The temp gauge isn't missing, it's just dismounted for shipping to me, and I didn't put it back into the cluster for this photo, here is a similar set ina  30's Dodge hot rod at the Primer Nats http://justacarguy.blogspot.com/2010/05/cool-instrument-gauges-in-old-1930s.html

Anyone know what vehicles they came from? I'm going to guess that the Chrysler gauges are from the 30's or 40's, but I don't recall ever seeing the bottom set.. anyone know what they are from? Such a low reading on the tach makes me think it was to a flathead, or a diesel.
