I was at a yard sale last week, and it was one of those spotty junk type sales. The little old lady asked me what i was looking for, and i said vintage tools. She says i do have a saw in the closet that i purchased 40 years ago, but never used, and she brings this out. I asked how much, and she says 25 bucks, so here it is. This is a type 12, which i could not find in my online searches. I called skil, and they emailed me the cut sheet for it. Last made in 1971.
