Have you tried it yet Digger Dun? I came here with the same question. I've been wanting to make some for a while. I have a bunch of old Hutch's with broken tops that I thought would be perfect for that.
If you haven't used the teak oil yet, you may want to try polyethylene glycol. It is the preferred preservative of wooden underwater artifacts. There are lots of sources online for its application. Very cool find, by the way!
I believe I have the same 7-up bottle. I'll try to post a link to where I found out some info on the labeling.

Thanks for the reply, that looks like a cool site. The second one sounds like mine. Funny thing, I didn't even notice that Berwick was misspelled until I took the photo and noticed that the C is actually a G. It stands out more prominently in the photo.

Hello, brand new member here, just found the site. I have a bottle I was curious about, couldn't find any info by googling. It is a dark teal color (I believe) possibly a mineral water bottle, not sure. It appears to be stamped with a plate R.BERGER
