Hello, I know coolsprings is the biggest collection of Springfields in the world and I have a question for you guys. I know a gentleman who was a 5 HP Springfield that is immaculant. Runs flawlessly and is a very late model number. As far as I know it is the only Springfield of any HP rating that has a mixer on it. Couple knowledgable guys checked it out and al agreed that the timeline fits for it to have one on. With hat being said, the gentleman was curious as to how much one of these is worth. If anyone could help me out you can privte message me or shoot me a text or call at 4843889719.
