Very odd, looks like partial scratcher, partial chipper. Maybe an attempt to get around Oregon's chipper patent? He says it is from an old shop, maybe VERY old.

I know I've seen something similar somewhere before but can't place it. Must be something for a specific manufacturing process. Possibly a chain mortiser.

That's an early scratcher, the type first put on chainsaws. They were patterned after the hand saws of the day. Some had 5 different angles to file. The chipper was next, the only chain that really worked for a long time. Then the semi and full chisel chains that are "modern". Maybe someone with a collection will step in here.

I thought so to, but it’s in 3/8 .050 I believe 3/8 came out in the early sixties. I did think anyone was making scratcher chain by then.

I have a Disston DO100 with a scratcher chain. It doesn't look like the chain on Ebay. I'm more apt to believe its used for mortising like jerseyhighlander said.

A poster online said it was designed by the government to cut trees with volcanic ash in the bark.

You may well be right about the mortising or other special interest. I meant that the chain from Acres site that jersey posted a link to was scratcher, not the ebay chain. What I said earlier was the the ebay chain looked like a combination of scratcher and chipper. :{)
