This is what John has to say regarding the Kingfisher and the Kingfisher II differences.
"I made some minor changes to the kingfisher. Mainly to do with the way I mount the ball bearings and also the porting of the spool..I did it so that if a man wanted some new bearings I would know what to give him by the name on the reel. It was also a bit of marketing BS, like "the new and improved Kingfisher". I have now found a better way of identifying the part and have reverted to calling a Kingfisher a Kingfisher. I also have changed the shape of the main spindle (centre pin), I am not sure it's any better or worse but the fishermen say that they prefer it."
The talisman MKII is the newer model of the talisman reels. I am not sure on the exact differences, it may be best to contact John to find out.
I do know that most people prefer the older reels as opposed to the newer MKII reels.
