Hi: Brunner's were originally a light blue. They are extremely robust. We often joke that they went out of business because they never sold any parts! Brunner has been kaput for close to 20 years now I think. If all is well inside, however, it should last you quite a while. Brunner's were never fast running machines, so I would keep the rpm's below 900. (no parts remember!) Having said that, there are often small caches of Brunner parts to be found in various places. A bit of digging may turn some up. We have quite a few dead ones here. We also have some parts, but there were so many models, having what you need may be hit and miss. Brunners usually had a small metal tag held on by one of the block bolts to give you the model number, like a carburetor tag. Without it, it will be very hard to find any parts. It may be cheaper to start over with a current manufacturer, unless of course you are restoring it. I have never heard of anyone doing this for an air compressor, but a Brunner would be a nice project. They were built like tanks and had some nice shapes to their castings. Shades of the steam era. Use a fairly low pressure valve in the intercooler, probably 70psi, although I don't know what Brunner used. DeVilbiss uses this pressure in their interstages. They are designed to pop when there is valve trouble. 5hp will kill a pressure switch. Use a magnetic starter if you go this route. 3hp is marginal, but you may get away with using only a pressure switch at this hp. Remember, you will draw twice as many amps at 110v as you will at 220v. Good luck.
