It is a pleasure to see the quality and pride that went into items manufactured in years gone by so the stainless valve set on a swiveling ball seat on the brass plunger providing an almost air tight seal should not come as a surprise but in probably one of the least expensive parts used on the Packard except for hardware it still is amazing . The stamping of the script logo and columbus with united states of america written out and not abreviated was interesting as the lettering alone probably cost more than some of the plastic parts used on todays supercars. I was wondering why the capilRy tube and bulb is not run into the heater box as in other manufacturers applications? Did Packard miss the mark here? It seems this eliminates the automatic compensation feature of the unit causing it to be just a manually controlled on or off. I read through the info on the refirb and a mention of ensuring to not damage the tube is made but in this case elimination of the tube and the tiny screw at the dashpot tip would give manual function. I assume the capiilary tube bulb would need to see the temp differential between 40 and 150 degrees as the other applications or did Packard have a different spec for the bulbs used? Seems unlikly. Strange the unit is sensing just the interior temp of the vehicle or more so the firewall temp.
