Gordon Air Compressor Conversion

[callcoy]

Ran across a Gordon conversion the other day on what I think was a A engine. Couldn't get thru the collapsed building to view the other side to verify if it was a A or B. Anyone familar with this brand? I know there is a Gordon Co. in Memphis that makes air compressors, I haven't contacted them yet, the usual response for 75 year old info. is "DUH". I thought I would run it by you guys, I know there is a special interest group for another brand but don't know how to hook up with them. Steve - Santa Rosa
