Rodney - STOP THAT!!!! I guess it's good I don't live in an area that has a plethora of vintage machines.
BTW - A.G. Mason is a badged White. There is some interesting history between AG Mason, Domestic and White. It does appear that early on AG Mason may have mfg some VS machines for White - but at some point they ended up as a White subsidiary, and finally it appears they are just another Mfg name that White sold machines under, maybe to help keep the "White" line separate from the "badged" machines. It does seem that the White machines with other names on them are often stamped as AG Mason Mfg. Well, other than the Domestic line. That's mostly speculation on my part, just from bits and pieces I've read here and there . . .
