CAN SOMEONE PLEASE TELL ME THE VALUE OF THIS VERY OLD OTTAWA VISABLE? BOOK I HAVE SAYS VERY RARE ONLY FEW KNOWN TO EXIST , MOSTLY JUST FOUND IN PICTURES,ANY IDEAS AS TO WHAT TIS IS WORTH WOULD BE APPRECIATED.

Ottawa visibles were made in Kansas by the Ottawa company who also made engines and garage hoists. I have found 6 of these pumps in the Colorado, Nebraska area. They are VERY heavy. Depending on the condition, I have sold them for 700-1100 for a COMPLETE pump with good glass. This pump has no sheet metal, it is all cast metal or pipe. It is a great pump to powdercoat.
