Here is a vintage 1968 Water Pik model 37 in cream, bone, or ivory and beige plastic. It is a family dental irrigation cleaning system with 4 tips. It is in excellent condition. I plugged it in and it does run. I didn't test it with water. It was made in the USA in Fort Collins, Colorado. The base is marked "Water Pik Oral Hygiene Appliance Aqua Tec A Teledyne Co. Ft. Collins, Colo." The model number is 37 and the serial number is 5A371.
