Dr. Grabow Pipe History Timeline

The following chronology is the work of Russell McKay, and is from his website. Sadly the link we had for this site has become malicious. It appears on Pipedia by kind permission of the author. 
Dr. Grabow Pipe History Timeline: I am adding at this point a sort of simple, condensed "timeline" of significant events in the Linkman/Dr. Grabow pipe history. A lot of this is not necessarily "etched in stone", and is basically a "working copy" of notes Mr. Bridges and I have put together highlighting things that we have found, observed or speculated on. Hopefully this will prove to be of interest and at the least, will be a good starting point for further research, comments and feedback:

We hope that you find the above information helpful or interesting and would enjoy hearing from you if, in fact, it has been or if you can offer corrections, additions or leads. I especially need copies of Dr. Grabow information from the RTDA Almanacs (copies or scans are fine!) for all years available!!!
Most recent news I have found regarding sale of the Dr. Grabow line of pipes and accessories to International Pipes & Accessories, LLC. An additional news article can be found at New Owner takes Over Pipe Factory.
And speaking of recent news -- and for delightful reading of the experiences of a typical Dr. Grabow pipe smoker, take a moment to read TOM MARTIN's great article at: Diagnosing Dr. Grabow: It's Elementary My Dear Watson.
