Late 1880s to early 1890s. A little harder to find in aqua than in amber, but amber draws more attention for obvious reasons. I'd say in the $10 to $20 range.
I've never seen that particular Nonsuch Stove Dressing bottle before. It looks older than any of the ones that I've seen, but I think Mctaggart's probably right on the value. I don't think stove polish bottles from that era ever go above that range unless they have an interesting colour or label.
They started in London Ont. in 1886 and by 1900 were in Toronto. In 1902 they registered as The Nonsuch Manufacturing Company Limited. I can't find them located in both simultaneously.
I was thinking that I didn't remember them being in London. I've got two of their bottles, but both the Toronto Nonsuch Manufacturing Company versions.
