You probably do have an error bottle there. The "Electric" oil bottle's embossing is very clear and crisp - signs of an under used or new mold. Also, the lettering is smaller on this bottle. Quite possibly, a new mold was prepared to modernize the font and the error was not discovered until some number of bottles were produced. More evidence of this potential - both bottles are typical clean blobs, obviously from the same time frame. Anyhow, my 2 cents.. Brian
Dr. S.N. Thomas' Eclectric Oil was Canada's best selling proprietary medicine from the late 1800s through to the 1920s. The medicine lasted until at least the late 1960s. There are hundreds of variants, ranging from hand-made corkers to machine-made corkers to screw-tops. I've seen spelling mistakes, including "electric," backwards letters, and a backwards front letterplate (all letters backwards). There are also variants with small lettering, large lettering, clears, aquas, and aquas with amber swirls. There are also ones from Newcastle, C.W. (Canada West, Ontario's name before Confederation in 1867). These are generally common, but tend to get scooped up into collections because they have a certain pizzazz, being older than Canada itself. Rarer -- perhaps rarest of all -- are variants from Newcastle, Ont. (Ontario), since they were only produced during a small window of time between whenever the "C.W.'s" were used up and 1870-71, when the firm moved to Toronto. Another hard to find variant is the 8-ounce machine-made corker -- not terribly exciting but a rare bird nonetheless.
