i have recently acquired a vizo pump, made by the boyle-dayton company, cut #74 with a serial number of 2968. it's in working condition, all original and under several chippy coats of paint i can see a union 76 decal. i'd like to know if this was originally a union 76 (or could it have been any other company). i've no clue as to how old it is. glass is in excellent condition, but it's missing the globe on top (if any). i can see screws (2) on the top of pump under the paint. any advice, guesses as to age, and info on the globe would be appreciated. i'd also like to know value as a semi-rough, operable pump and what i'd have if i cleaned it up and repainted. kinda new to this.
thanks!
