I have been searching through the various threads and even my gas pump books. I recently purchased a Bowser model 41. The odd thing is that it has a flat edge top along the top where all of the other ones curve. On flat edge or shelf is a keyed lock assembly that allows a piece of steel to slide back and forth and will not allow the vertical crank to rise when cranking the handle unless its unlocked. I was just curious if anyone has encountered anything like that.
Thanks in advance
