Here is a very nice and small original Brunner Air Compressor with a base and flywheel castings.  Many people have used these little compressors to make model gas engines.  I bought this setup at a swap meet last year.  The compressor seems to be in good shape and has some compression or vacuum.  It has a very small chip out of the base by one of the mounting holes.  One of the flywheels appears to have a casting flaw that was ground on or filled in a bit.  Check out the pictures and see if you need it.  For questions 419 789 1159
  • Great looking
  • The bore is about 1-7/8" in diameter but it is difficult to measure so that might not be perfectly accurate
  • The stroke is about 2" 
  • The crankshaft is about 15/16" in diameter
  • The base has a chip by one of the mounting holes
  • The compressor on the base is about 12-1/4" long in overall length
  • The flywheels are about 9-3/4" and 10" in diameter, one just appears to have some extra iron on the rim, the should machine to match
  • No plans, make it however you want!
  • Heavy! It's all about 42-1/2 lbs before any box or packing material.

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!
