I picked up a siphon bottle this week but I can't find out anything about it. Well, almost nothing. I did find an copy of an old photo of his bottling company in Vernon online from the Vernon Morning Star. It shows the interior of the building and says the company was called Vernon Springs Bottling Works. The photo says it was owned by M.J. O'Brien but that is it. I can't find any bottles made by his company. The siphon is an ordinary one with an oval on one side etched with M.J. O'Brien, Vernon B.C. and what looks like a fancy fleur de lis design in the middle. The top is also marked with M.J. O'Brien. Vernon B.C. I found mention of a bottling works in Vernon with another name in the book by Bill Wilson. However, it doesn't say who owned that company and I can't find any other mention of it either. That company was Okanogan Valley Soda Water Works. The bottle looks like it will be nice for a plain bottle if I can just get the top off. Tried alot of the ideas mentioned here and the lid is still stuck. As the sealing ring is lead can it be heated a bit to loosen the top? Thanks for any information on O'Brien or how to get that darn top off.
