Oregon Sprocket numbers from the 70's

[Madsaw]

Just wondering if anyone has a source for looking up oregon sprockets from the 70's. I do not have any books that far back to look some of them up. Also the same for windsor and herr sprockets.
Thanks
Bob

I would also like to know where to find that info as I have boxes that contain hundreds of mostly spur drive sprockets from mostly the same makers as you have posted.

I can look up Oregon numbers but I cannot remember where my Herr books are.

NPA, inc. had Herr sprocket charts but they are no longer available. Not sure how far the list goes back.
Using the Internet Archive (Wayback Machine) found the old NPA site. You can click on the manufacturers and get the saw sprocket info. There are about 8 pages of info to save.

Thank you Ray, I copied it all and will have it for future reference. Now the detective works begins.

That NPA site was one of the best ever for IDing old sprockets.

Mfg supply uses Herr #s as their part numbers, so you can cross-reference Herr #s here: http://www.mfgsupply.com/ChainsawSprock.html

Now is the time on sprockets when we dance!

Jerry, how did you copy that info from the site, as I would like to do the same?

Found this thread searching for NPA - today I merged the 8 pages of sprockets into a pdf .
