Thanks for your reply and input, much appreciated. Planned on including some pics but can't figure it out..lol. (my first forum experience....hence NEWB) I have done ALOT of research and have learned a ton about bottles in all aspects....but as you know I'm sure, is and ocean of info, facts, and history to glass bottles. Which will take some heavily invested time and dedication to learn and know what your doing in confidence, as with any other such collectors hobby, trade skill, historical subject, etc., etc. does. Which I will indefinitely be doing as I find it captively intriguing.It depends on the exact version of the bottle and the condition, but generally I think the 4" version in excellent condition runs about $100-$125, but there are some variations that are tougher to find that might bring that a bit higher. I believe they date from about 1900-1920 or so.
