I worked at an Edward's Pipe Shop in Jacksonville in the 70's and I can provide more information about Edward's pipes. Edward's still exists with a few remaining shops around the country. Like the rest of the industry, they are primarily cigar stores and gift shops now. Edward's pipes were and are their house brand and they were made in their factory in Tampa. I visited the Tampa store several years ago and they told me that Edward's pipes are now made in Spain. They also told me that they were running out of Algerian Briar and, as a result, many of their pipes were no longer carrying that stamping.
If you are familiar with Randy Wiley pipes, he started out making pipes in the Edward's factory in Tampa back in the 1970's.
The models Skylark, Skipper, Royce, Benton, etc. are fairly recent name categories, probably starting in the 90's. They didn't use these names when I worked there, except the "Skipper" was a pipe with a particular style of etching on it. At the time they made some very nice high-grade freehands that sold in the $100-150 price range (several hundred dollars today).
While the individual Edward's shops are franchisee-owned the parent company is FGT Enterprises of Tampa, Florida. The company makes pipes under the "Benton" brand for other shops around the country, and makes private label pipes for some shops as well. They are a leading wholesaler of smoking accessories. You can go to their website and download their catalog (www.fgtenterprises.com--you might want to check out the "About Us" page on the site. FGT at one time did not stress their connection to the Edward's shops, as they wanted to downplay the fact that they were associated with stores that were competitors to some of their other customers.
I have about 20-30 Edward's pipes from the time I worked there and they have always been good smokers. The only problem with them is that pipes in the 70's tended to be smaller (about group 3) than they are today.
As far as I know, there are still Edward's shops in Los Altos (CA), Englewood (CO), Tampa, Atlanta, Jacksonville, and Dallas. In case you are interested Edward's was named after Edward Rowley, a Tampa TV personality of the 50's and 60's who founded the company in partnership with Frank Smith ("Smitty"). Rowley was essentially the "face" of the shops while Smitty was the tobacco and pipes guy. Smitty bought out Rowley's interest in the company sometime in the late 70's or early 80's.
