What Bar is This?

[Alaskan Stihl]

Help!
I recently got another chainsaw to throw in the collection (Stihl 026) and discovered that it has a “Oregon Bar” on it.
I tried looking up the numbers on the net, but surprisingly…I didn’t find a thing. Can anyone give me any information on this Bar? Here is the information:

Oregon
Made in Canada
7730 EM
200-H025

It’s a 20 inch bar the H025 is a bit different but it’s most likely a different variation on the D025 12mm Stihl mount usually Oregon does this when it’s an odd drive link count.
