Robert Shaw - also sold under the Mr. Gasket name, it has a "fail safe" feature that locks the thermostat open in case it fails, instead of shut like lesser thermostats do. Try the Eckler's catalog, I am pretty sure that they have them.

There are some thermostats that are advertised to fail open. Since they start out closed, if it did not open, then it fails closed. I may have posted that before.
Anyway we tried one on a Mopar in the summer. When the weather turned cold, the Mopar ran cold. Checked the thermostat & it was locked open because as it warms up & opens enough the clips added to a normal looking thermostat catch it & hold it open. It was released & tested on a stove w/ the same result.

Here is the Rober Shaw marketed by Mr Gasket and sold by Advance Auto or online by their Parts America
They stock them around here, but take the part no with you as the help usually can't find it.
