I'd disregard anything produced by "Lentheric" now -- (I put it in quotes as it is Lentheric by name only).
Due to a long of history of acquisitions, products by Lentheric have are now made by various people. If you look at the Lentheric products now in production:http://www.basenotes.net/house/10051...=In+Production
You'll see the more famous brands are now made by Mayfair and FF&C.
A bit of history:
The house was founded in the late 19th Century by Guilaume Lentheric - a hairdresser with a passion for perfume.
I have a big gap in my knowledge until the 1960's, when Lentheric was acquired by British-American Cosmetics (A division of British-American Tobacco), who also owned Yardley, Montiel, Tuvache and Gres (amongst others..)
In 1985 BAT decided to get out of non-tobacco industries and sold off its cosmetics lines. Most of which were picked up by Beechams.
In 1989 Yardley & Lentheric were picked up by Wasserstein Perella (who at one point also owned Maybelline). Yardley and Lentheric were run under a new company named "Old Bond Street" and were also responsible for the So ...? teen brand.
1997 saw the companies go into liquidation, and here is where everything gets all split up and messy.Fine Fragrance & Cosmetics
buy some of the brands - Lentheric's Tweed and Panache (as well as Yardley's Lace, Chique and White Satin).Parfums Bleu
buy some of Yardley's men's brands
Wella ends up buying the rest of Yardley, and Swiss company Incos by So...? Cosmetics
As for Lentheric -- it is purchased in 1999 by a UK company Shaneel Enterprises. (who had also bought Worth the previous year)
In 2004 Shaneel changed the name of Lentheric to "Mayfair" and sold the Lentheric name to a South African distributor who now make a variety of body sprays etc under that name. Mayfair still produce a number of Lentheric products, but it may be worth checking eBay for classic stuff
