I believe this model 200 was one of the first off the production line, or part of the first series. Date is 2/51. It is unique in that the frame rest is embossed with the model 242-299 generator as the replacement to use whereas later models are embossed with "use T-66 generator". This 242 type collar was used only for 2 months of production. Pump cap screws are not original and not sure about the globe.
