Boos,
Checkout this old link to a 300,957 Inland I came across. It will show you the two tone finish. Some of the pictures were before cleaning. After inspection I added pictures of it after cleaning. There is a long slide show that I believe still works and links to the original owner.
It's a very nice example of a nearly pristine carbine.

Will anyone who opens the link above and then clicks on 'The Slide Show' Let me know if the link works for you..... Thanks
