Eddie,
I dont recall any other marbled color but there may have been a black/white and a brown/grey?! I wasnt able to find them in my old catalogs from the 1990's at all. Older ones had them pictured, I am sure, but those cataloges I gave away to interested fellows back then. Never thought I might want to keep them - for later collecting purpose. I was so dumb
The marbled Björn nocks are gone since about 1995 I guess. But Björn nocks also came in different solid and transparent colors of course. They can still be found here and there. I am not sure if Bengtson actually had quit production. A while ago I was told they just can not produce enough, thats why they are somehow hard to get!? There are fakes out there too, which some shops dont mind selling as "Björn nocks" - when they should say "Björn style" at least :mad:
