Hi, on the M&S 80, is the sight glass in the the top above the door any older than the ones with the sight glass behind the glass or vs versa, or diff in value, can the sight glass be relocated if a script top is put on?
The MS 80's were designed to be customized by the oil companies. All were basically using the same prototype from 1946 but variations made depending on company request. The site glass manifold can be moved below the top internal frame plate to convert the pump to one accepting a Script Top. You'll have to do other adjustments as well but it will work.
