What kind of chain is this?

Looks something like some of the old ice cutting chains. Most of those were 3/4" to 1" pitch. They were used for other purposes as well. But I am only familar with the Ice ones . We were still regrinding those in the late 80's. Up until few years ago there was still one of the old ice storage buildings over on Pewaukee lake - Made the news when it burned down. Ice was sawed out of the lakes in winter ( including Lake Michigan) and stored in the big Clapboard warehouses packed in saw dust. Before electric was real common your refrigerator was called an Icebox as a large block of ice was placed in the top and food stuffs below. It was quite the industry. Up til about 10 years ago I was still making bars and chains for one company in Milwaukee to resize the big blocks of ice that their machine made and sharpening blades for a machine that would shave chips off the smaller blocks for various drinks and snow cone type stuff. The new ice making machines have eliminated all that. Of course the blocks of ice from lakes are no longer considered safe by the various health departments.

Looks like one of them stay sharp chains that have the proprietary bar and attachment on the end that sharpens the chain. Interesting chain with dual depth gauges.

Oregon PowerSharp chain.

They sharpen the cutting bevel on the top of the cutter, instead of on the bottom (like conventional chains).

The 'diamond' logo embossed into the tie straps refers to the diamond embedded dressing link in each loop, for the sharpening stone.

Designed to be used with proprietary PowerSharp sharpening system: 'On the Saw, On the Job, in Seconds'.

A brief google peek only showed me the link to Frawleys and the Carlton chain reference.
Any chance that your chain is .325 pitch?
