I saw this C.A.W. aluminum valve cover up for sale, and was curious about the history on it. It came off of a '46 Chevy according to the owner. I hadn't seen one before, and was thinking of buying it as a polishing project. It has a patent number, which is interesting for a valve cover. Anything 'ya know would be appreciated- Thanks in advance.
I had one.Asked around here in denver and came up empty. Maybe 40studedude knows? I've seen a couple pick ups here with them on. Kinda plain,but different anyways.
Cool as heck, I would dig one of these for my stovie. I have read someplace that CAW stands for Colorado Aluminium Works, but it is no longer standing at the address on the manifold. They were supposed to be used on milk trucks to cut down engine noise. Hope this helps, perhaps a real stovebolt expert can chime in and correct me.
I did find a little blip in the HAMB archives referring to the C.A.W. being used for reducing engine noise on trucks, that must be what the patent was for. Still kicking around the idea of buying it for polishing.
Dragging up an old thread here as I just bought a caw valve cover from a fellow hamber and was searching around for info on them. The patent number 2607331 is now in googles patent database. http://www.google.com/patents/US2607331 The C.A.W stands for Charles A Wefing and the patent is basically outlining noise reduction. "not responsive to the pitch of noise produced by the mechanisms enclosed within the cover, and thereby to prevent such noises from being transmitted outside the cover". It has a detailed drawing with measurements. Interesting reading. cheers ricki
