Hi H20Doctor! A couple of neat bottles!
1. The Thos A Edison battery oil is quite common, and dates from tabout 1910 to early 1920's. They were used along old telegraph lines where a non evaporative surface was needed on the large acid filled battery cells that boosted the signal thru the wires. In other words, the battery oil protected the acid from evaporating out of the booster cells. Interesting that you found one of these diving, as they are practically all found along old railroad right of ways where they were dumped after use. The oval style of your bottle is the middle varient in terms of age. There is a handblown example of this bottle with tooled lip from the 1890's-1910 period, then your machine made cork top example from 1910-1920's. The last variety is a smaller round embossed bottle, same lettering, with a bottle cap style top.
2. The Gordon's Dry London gin, of course, is a British bottle. Yours is cork top rather than screw top, so it would date from the 1920's. I've usually seen these in a square bottle that is quite common. Your style is one I've not seen before, but would say not much collector value, but rather a good historical interest and great memory of finding it!
