age of Weil Mclain boiler

[Andy Shapley]

Can anyone give me an approx. age on this boiler - all the serial / model numbers have worn off. Notice the phone number for the oil company

Looks like an old Wayne burner with a J pump, probably early seventies.

I have been trying to determine when WM stopped using the type tag that is on this boiler. So far no luck...
