Rare Paradox Cast Iron Engine Toy. Only marking is "Pat Nov 20 1900". Fly wheels turn freely (feels like it might have a little compression). Needle valve turns freely. Looks like it could be original paint. This is what is commonly known as a "Flame Licker" engine. It is not a hit and miss engine, nor is it a steam engine or hot air engine.

Please feel free to ask any andall questions, I will even answer questions that are alreadyanswered in the description although your intelligence may bequestioned :) I am 100% certain that no one NEEDS any ofthe items I sell to meet any basic needs of life. With thatsaid I am selling these items for the money and if you cannot pay, think you might not be able to pay, or do not want topay please bid on items owned by someone else.. If you haven'tcaught on this is supposed to be mildly funny but yet serious at thesame time. I donot end auctions early—its not fair to the other bidders. Most ofthe items I sell come from estates and I sell them in “as foundcondition” – I leave any cleaning or “enhancement” to thebuyer. Please check the pictures –they are probably the mostimportant part of the description. Ifthere is a problem with any item you purchase from me, let me knowimmediately, I'm sure we can work it out to your satisfaction. OccasionallyeBay calculates some wildly inflated estimates for shipping costs, ifthe estimate doesn't look right, contact me for confirmation. Ialways specify USPS priority Mail – if you would prefer anothermail rate, please let me know. I never charge more than the actualpostage cost, and I will rebate any excess, over a dollar to yourpaypal account.
