I recently posted pics of a Wayne 615 that I had recently purchased. It seems like I read in another posting that you can tell the age of the pump by looking at the brass plates. Is that true? And if so can anyone help me date my pump...I have posted pics.
Thanks!

Good MORNING, My Blue Book indicates that Wayne 615 SN 100-W through 10652-W to be made in 1929. Assuming the production was consistent every month, that would be about 880 pumps per month. Yours would be a February pump. OR something close.

Wow...thanks Neil for the information!
