I do not believe it was made without a liner. Main reason is that there are no o-rings at the top or anything of the sort to prevent leaking. Also, the tube insert to me matches the period where the glass distorts when you look thru and it fits so well that you just "know" it was made for this. The paper that was included with this find says that this is the only one known with a liner, though of course I don't always believe what I read.
Thanks for the input, GREATLY appreciated!
Hi,
While there is room to discuss originality of the glass tube, do note that the paper cited would appear not to be at all helpful. It is merely an after-the-fact claim.

Understood! It just fits so perfectly that it would be hard to imagine it being from something else. Thanks again for your knowledge!
