Some more info.
All the ads I have for Birmingham are from 1926 & 1927. The same picture is used in every one of them.
1926: ad states it comes with foot valve, hose, hose nozzle and lock. States both 5 gal. & 10 gal. 10 gal bowl fills in 16 seconds. Has two sets of brass gallon markers. They call it the 400 UD Birmingham.
1927: takes only 11 strokes to fill the 10 gal. bowl. Wired for light. Six strokes and eight seconds to fill the 5 gal. bowl.
