OK all this talk about the Don Clark Eureka nozzles enticed me to get both of mine out this week. The actual Eureka one last night and my Airway one tonight.
This one is dated 1972 and goes with my model 88 sanitizer mark 2
See the difference in the 2 different ones? They have the same model number except the Eureka starts with C for commercial. I wonder if the last version of this (white and gold) is also a 1250???
