1932 dual guage

[Ian NZ]

David When my dual temperature gauge was overhauled in U.S.A I made a jig and I made several face plates but they have to be sign written by a sign writer and I still have several of them left over. The fluid in my Temperature gauge has now gone clear I would like to replace it, is it the same fluid as in the Fuel gauge, and I would like the full procedure in replacing it and caibrating the gauge. It looks like it goes in the probe end 3 and sealed with a screw.
