Looking for some help from all our fellow gas and oil collectors. We came across this awesome barn find. Bowser self measuring pump with patent dates 1909-1912, with the original glass and I.D. tag. We were told it was for pumping oil in either pints or quarts. I have searched and searched and cannot find another one just exactly like it, especially with the glass tube on top. Thanks a lot for your help with ideas of value.
