Thank you all for the info, very helpful. Picked it up yesterday. looks to be in pretty good condition. It is Grey and plate has stamped on it "Model 30-1" with S/N of "116346" . Been trying to find the year of manufacturer on the net ....but no luck ....anyone have an idea of how to find that out? I did find a manual and downloaded it. so will be playing with it in a few weeks.
