I found a NOS sleeved SMITHS thermostat prt. nr. 85025/74 (74:C or 165:F) in its original box. I do not know the application. Is it one for one of the Healeys? I have had it in one of my boxes of "old junk", parts of unknown application, for many years. By the looks of it it is from the 50's or 60's Kees Oudesluijs NL
