Reading this thread made me think about my score in August. I was rummaging around a junk shop in NE WI and ran across a Porter Cable BK12 12" circular saw from the 50's. It was a little pricey at $90, but I plugged it in and fired it up. It ran, but the bearings were trashed. After pointing this out to the shop owner we agreed on $70. Since then I tore it apart and have done a complete restoration of it. New bearings, polished all the aluminum, new cord, stainless hardware, all new grease, and just waiting to get a blade bushing for the 3/4" arbor. It's a beast at 38 pounds, but BOY what a beauty. I'll try to post some before and after pics in a new thread.
