An illustrative example how the consumer preferences changes over decades. Todays smokers are usually interested in pipes marked "large", "extra large", "incredibly large" and so on and so forth. Such the trend arised the most probably after the end of the WWII and many leading manufacturers such as Charatan's and Barling were involved into this race.

It would be very much boring if everything was unambiguous and transparent with pipes origin history. But, fortunately, not all producers behaved as Dunhill with their obligatory nearly hundred years stamped year suffixes (however, Dunhill was not always pedantic too :-)). Here is, for example, a very rare (some collectors write "extremely rare") Loewe & Co model. The marking "London W." specifies that the pipe has been made at family London factory in Haymarket. At the same time hallmarks on a collar specify London 1981, i.e. after the acquisition of the company (approximately in 1976).

The Frenchman Emil Loewe was seemingly the first in England who started making pipes of briar in 1856. And he was seemingly one of the first introduced "military" mouthpieces (spigots) - for a simple reason to facilitate the production of replacement stems for customers. Since then and till absorption by Cadogan in 1979 Loewe occupies strongly a niche of the one of the most successful and collected trademarks in the upper middle segment. This pipe is made not later than 1967, it was smoked moderately and very accurately. And of course "Birmingham" means not a place of production, but the model name :-)
