Hi Guys! Recently the topic of pre-visibles came up and their seemed to be a fair amount of interest in them. I've always liked them, and through the years accumulated 3, 2 55's and a 65. The 55's are serial numbers 185 and 318. The 65 has no number stamped. There are several subtle differences in the two 55's. The earlier one doesn't have the cast GB fitting on the stand pipe, has "button" markers instead of the more familiar marker strips', no provision for a light bulb over the gallon indicators, and the racks that operate the pump cylinder are enclosed in brass tubing. These guy's all came from local farms and man, are they rusted tight! Anyone out their have any info or restoration tips?
