Here's something I never expected to turn up. Real whale oil.

Wm. F. Nye "Finest Machine and Household Utility Oil" bottle from New Bedford, Massachusetts, dating back to the 1920s or 1930s.

Back in the day, Nye was famous for refining sperm whale oil because it was the absolute gold standard for high-end sewing machines and watches—it never gummed up or froze under extreme temperatures.

It is legal to have it, but because of modern wildlife protection laws, I can't legally sell the 90-100 year oil. I could drain it and sell the bottle alone, the label is fantastic. I would rather keep this fascinating bit of history in my own collection on display in the shop.
