Almost all of the reproduction items are below par set by the
factory.
I've also got a repro temp gauge in my '50 and it sticks.
Reads correctly when it decides not to stick.
Problem with the vast majority of the repro stuff is it's made
in tiny back alley shops somewhere in communist China where
there is no such thing as Quality Control. If it physically
looks like the original item then ship it, someone will sell
it and someone buy it since no one here in the states can
afford to make good reproductions. Mar-K, US Radiator and a
few others manage to be the exception and they seem to have
found a way to make good parts and still make a fair profit.
