Haven't seen this one before, looks factory-ish or else someone did a very neat job of it. Showed up on a jred 2051...

Doubt It's race stuff with the bumpers still there, was a homeowner saw that he got from his brother in law so no real details of origin.
Was rocked pretty bad and I had to grind quite a bit off to clean up, I should have taken a pic first, the undercut was very pronounced with the closer to full length cutters.

I remember the late 1980's having it at the dealership I worked at
I believe it was an intermittent between ansi approved low kickback and professional chain. I used some of it over the years and was happy with it. Probably not the best for boring, but if your not boring a lot, not much difference from pro chain imo.

I missed the undercut there. Looks like someone tried making it more aggressive with a grinder. I don't know if he understood what he was doing.

I dunno about that chain, however I do know that a Jonny 2051 is a very nice pro saw, that is relatively uncommon.

A bit over aggressive cleaning out the gullet.
