Captain,
took a while to track down on line, web site has changed. Anyway, the cleaner and conditioner I used on my gobi was by Gliptone, but the dye is available from:
http://www.daytonagblimited.co.uk/le...yes-gt30-.html
I did manage to find a list on line, which showed "Gobi A577"
Hope this helps, I may contact them for my Nordkap. Let me know how you get on.
annoyingly I deleted the before and after photographs when I sold the R, but it certainly improved the look, the dye gets into cracks etc. and blends them in with actual leather.
