i am researching this to try and find date and model number it has a serial number f9498663. one place had 1909 another 1910 to 20 and another had 1924. the lady i purchased it from never used it. it works (excited excited) but need to get a manual for it. oh and it had a can of pounce in it made by keuffel & esser co. the can looks really old.
