Here is a pretty nice 3/4" New Judson vertical flyball governor.  It is pretty tight with only a very minimal amount of wear.  The valve in the bottom appears to be complete and in good shape.  I think this type of governor would be used on a Bessemer oil field and possibly other gas engines.  It should also work with a steam engine.  There is a very small repair on the drive pulley but that shouldn't hurt a thing.  I am not an expert in governors so please check out the pictures and see if you need it.  For questions 419 789 1159

I am a well known collector and dealer of antique gas engines, parts for them, and related items.  I try to list all my items very accurately so the buyer knows exactly what they are buying. Out of respect I ask you to please actually read the descriptions and look at all the pictures before buying or asking questions.  I am glad to answer questions but I’m not always that good at emailing people back. If you can find a way to talk to me with your voice you will almost always get a quick response. If you message me please try not to sound like a caveman.  I have terrible grammar myself so I understand but sometimes it is very difficult to comprehend what some people write.


All of my items are listed “AS IS” and “NO RETURNS”.  If I make a mistake on my measurements or you feel something is not as described please let me know and I will try to make it right.  I think most all of my customers with a normal level of sanity are happy.

My shipping time is set for 5 business days, weekends and holidays don’t count.   I ship out most items quicker than that though. If you are worried about how soon I can ship an item please ask before you buy it.  I travel a lot and have a family so I am not always on call 24/7 when it comes shipping items. I think most people would agree that I do an extremely good job of packing items so I guess it's worth the wait.

Please keep in mind I also really like to buy collections of gas engines and parts.  I pay very well and am a very active buyer. I am looking for items for my collection and resale.   


Thank You!
