Your Berg has been severely modified in the critical chamber area and it looks like they used a chainsaw. Plus, I'd say it has had a re-facing or attempted one, and the tip looks crooked.
What they mean when they say Berg's tips were 'wrong' is they usually were not exactly as stamped. So your .115" maybe was more like .113" or so. Now, I would guess it at .125. I would say at this time it has no value unless it just happens to play great, but you would have to convince somebody of that.
What it looks like a work in the chamber area does not look like that in person, really. Reminds me more of when humidity attacks a painted wall and the the paint is just almost to fall(sorry my english is limited).
Tip is not crooked, maybe those are not the best pictures I have taken.
Tip opening feels to me like 115 or even more, maybe I'll try to measure it with a caliber. At first I used a Lavoz medium fresh reed and it worked but I found it easier to play with softer reeds, so I'm playing blue Vandoren, 2 strength.
It plays really great, I don't need to convince anyone, I only want to find out more things about this piece and Bergs in general.
I've found another for sale, 110/2/sms, and bought it too so to compare and try a different tip(hopefully smaller)
