I have had this 4 cylinder in-line compressor for more than 10 years, its older than Moses himself and I am certain there aren't any parts left in the word.
All that being said I am throwing it out there for help in identifying it and seeing if there is the slightest chance someone might have a crankshaft.
It's super quiet and I used it cool a grinder I use for drill bit sharpening.
If anyone can help me ID the unit and any possible parts it would be appreciated. Many thanks in advance
