I emailed DW with a couple of questions regarding all of this, and this was their response: I thought this was really weird, I have the same lugs, the same finish, the same shells and the same DW heads as the Collectors series, the only difference between them is the badge, and on top of that there is no official information of this line anywhere (let me add that I bought this shell pack from a DW endorsed artist, and he bought it directly from DW a couple of months back). Like I started saying, I just bought a NEW Workshop Series, and they came with regular round DW lugs in Broken Glass finish.
It was said that they stopped making them because they were so good that it was affecting the Collector series in terms of sales, and so it was later decided to make the Pacific line instead of Workshop. I found some information that basically described this series as a line that came before Pacific or PDP around the year 20, and that they came in three different lacquer finishes with oval lugs (just like the Pacific line) and had a different badge that said DRUM WORKSHOP. I just bought a new shell pack from this line, and because I couldn’t find any information on I tried searching for them on google.
Hi there, I would like to contribute with a little more accurate information on the DW WORKSHOP SERIES.
