From left to right #1-#17 including the large painted pump are an early style 1910's through to about late 1920's Coleman lamp and lantern pumps, first 3 are 7" pumps for irons, next 5 are 11" pumps, next 8 are 10" pumps, the large pump in the center is painted brass, but I've also seen these as nickel plated and unpainted brass. #18 through # 25 are later Coleman 1930's through to 1950's pumps as they have the brass pump shaft collar, shorter ones are 7" iron pumps, longer are 10" lamp pumps. #26 is an AGM pump #27 and #28 are unidentified and possibly medical pumps but work great for pressuring up lamps. #29 is unidentified and looks similar to Coleman but has a different type of shaft collar and the wooden handle is smaller.
