Hey all you allis people, I am looking to add a d 19 lp to my collection. This will be my first Allis since I was a kid. The owner has asked me to make him an offer and I am lost as to price. The 19 has sat fot at least 2 years and the LP engine is stuck because the exhaust ran cap stuck open. we all want the best price we can find but I want to be fair. The tires are about 80% and the paint is decent for it"s age with the left hood panel missing,he said it popped off and he ran it over. The owner thinks it"s rare ( I hate that word ) because it"s an Lp tractor. How many were produced? What would be a fair price? Thanks every one
