If you go over the DoubleGun BBS and contact a gent who posts there as
'Eightbore',,,he is a very knowledgeable about John Oberlies and collects his firearms.
I believe his first name is 'Bill'.

You will have to register to be able to contact him.
Then you can send a PM or email through the Forum.
He is very active on both the SxS forums and also the 'Classic & Custom Sporting Rifles' section.
The latter section he has posted quite a few times about Oberlies rifles.
He was collaborating w/ Michael Petrov on a new edition of Mr Petrov's book on 20th Century American Gunsmiths to include a chapter on Oberlies. But Mr Petrov passed before the book was finished.
Hope this helps.
The only thing I have from J.Oberlies is a 1895 Winchester that was stocked by him. It has his deeply stamped name & Dayton,O. marking in the butt stock under the plate.
The metal has been polished and re-rust blued, I think a later addition, not up to what I'd think of as his standards.
