I did pick up some McConnell's last night (5x 50g tins)
was looking to get Wellauer's also...
If anyone is familiar with both and can say that they are similar enough not to warrant purchase of both would accomplish the same thing as finding a source
Rajeks House of Smoke (Germany) used to carry it: http://www.rajek.de
You can also try an Advanced Google Search using .de as the domain (Germany). Also, check under Planta - I have noticed that they are now carrying Wellauer's pipe tobacco. I think Planta produces and/or distributes the pipe tobacco blends for Wellauer's. I've tried to get a hold of Wellauer's Latakia but came up empty handed. They may have discontinued it. I did see it on Ebay once about a year or two ago. Good luck!
