Head removed from a smaller size Nelson bros hit & Miss Built engine. Typically tagged as a 1 1/2 or 1 3/4HP engine. Please research and do some measuring before purchasing this head to make sure it’s what you need! No breaks or welds that I can see. Good 1 NPT threads on the exhaust. The 4 mounting holes are spaced 3 7/16 apart from each other on centers. The valves have quite a bit of “slop” (wear) In the guides. I’ve seen many engines run that way and I imagine with a good cleaning and lap job to the valves they would work just fine. Keep in mind this item is over 100 years old. It’s old and used!!
