Cancel ID Help Needed

This is an item I have been lusting after for quite a few years. The dealer initially wanted an INSANE price for it, but after I was able to prove its faults to his satisfaction, we finally were able to come to terms this year at INDYPEX.

However... I'm not happy with what he did in order to satisfy himself that I was correct... rather than just using higher magnification to examine the piece, he committed the cardinal sin of soaking tied part perf stamps from their document piece. I still have high-res scans that he originally sent me showing the stamps tied, so I am not concerned about possible authenticity issues.

Where we disagreed on price was that he originally considered it a pair, when in fact the two stamps were separated and the left stamp was torn in half... no way I'm paying anything close to the pair price for this. Once he verified my assessment of the condition, the price came way down. I have reconstructed the pair from its pieces in
order to show the complete cancels.

Anyway, the draw is not the stamps themselves, but rather the cancel.

It is a very ornate negative (customs?) cancel that appears to read:

JUNIPER * DEAN * STREET * LONDON

and is dated March 24, 1864.

To date no one has been able to identify the company in question.

Any information would be appreciated.

I did find a Juniper [Barrister] in London, circa 1866. Wikipedia contains a very interesting article on "Dean Street," and its connection to famous persons, including Mozart, Marx, Engels, and Lord Nelson.

John Jupiter of Soho was a chemist and apothecary with premises in Dean Street.

edit- and so was John Juniper He patented Essence of Peppermint and his company sold to agents and captains crossing the Atlantic. Looks like an apothecary's jug on the JUNIPER.Dean.Street.London

I notice this morning that my URL was changed, something about shortening; why do we prohibit such a useful feature?

Yep, that looks like the most plausible lead thus far. Someone on another board posted a link to this article:

The article doesn't go into much detail as to what happened to the business/brand name following Juniper's death in 1798. My assumption is that the business still existed in 1864...

John Juniper had exclusive rights to his patented peppermint essence "medicine" for some time. After his death the company was then appropriated by someone called Heath. Not being a native plant of the USA, the peppermint essence (and presumably the plant also) was imported... usually by agents and there are adverts in some old newspapers asking captains of vessels to contact the agents for a return cargo (captains could make extra cash that way).
The Entry Of Goods revenue stamps, probably taken from some a cargo manifest or similar document, would indicate there was an importation of goods from the Juniper company of London and what would be the Juniper Company logo appears there too.

John Juniper got his idea for Peppermint Essence after a visit to his doctor. He asked the doctor if he could have something for wind. The doctor gave him a kite. Rather deflated by that John Juniper decided to invent a remedy with, in his own words, "the virtues of speedily relieving Cholicky Pains, and all Disorders arising from Wind or Flatulency".

This would indicate that the company was still active after the death of John Juniper...
The famous Bielby & Bewick workshop in Tyneside produced a mould for a Type 2, bottle embossed 'Juniper's Peppermint sold by J. P. Heath' , in March 1812
