This ad is for a used internal engine oil thermostat for a 1972 - 1989 Porsche 911. This is a Behr Thompson 7 - C thermostat and aside form a thorough cleaning and replacement of the missing O-ring would be perfectly suitable for re-use. I have two of these for sale.
The Porsche part number is 930-107-765-00
I am asking $75.00 for the part, plus $6.50 in postage and paypal fees
