Temp gage acting stange

[deuce lover]

I've got two NOS '36 gauges and upon close inspection find the tube is stationary - no allowance for adjustment. Also, the face plate fits in one registered spot.

Thanks Kube for reconfirming that.

My problem has been resolved. I swapped in my old temp gauge and it works fine ( except the color is gone). I will send my new gauge back to MAC's and old gauge to John Wolf for refurb. Thanks to all for your help.
