For your kind consideration, may we please offer you the much sought-after piece, original American-made antique Triple Cylinder air pump. Made in the Rochester, USA. While its exact age cannot be verified, it was most likely made in USA before the Great Depression Era. All parts appeared to be present and original, except perhaps for the rubber hose. As expected, the rubber hose (cloth-lined) has stiffened and cracked over the decades, however, a replacement rubber hose can easily be located. Please study the pictures carefully, as it is the condition in which you will receive. This is a rare item only reserved for a collector with taste and proper social standing. It is a relic of our great American history, and evidence of our contribution to the industrial world and civilization. It contains dents, scuffs, scratches, chips, dents, dings, marks, rusts, imperfections, etc., that are consistent to its age. You are bidding or buying this item with this realization in mind. It is not a new or pristine condition but an antique in used condition. You are not buying some brand-new reproduction crap you find in stores today. We had attached a photo copy of 1919 Patent US1357402, filed by the inventor George W. Kellogg, for your reference only. This was patented on Nov 2, 1920.
