I’ve had both the jap and Taiwan models completely apart side by side thanks to
@Terry Harman and his vast collection of them needing some service and tidy up work.
Visually the differences are quite subtle. The main gear is different material and looks to be finished a little nicer on the jap models but there’s nothing between them really until…. You button them up and turn the handle.
I tried and tried to get the 2600 to feel like his 30 year old 1000’s and failed miserably. They are nothing alike and I can only put it down to part tolerances because visually they should of been the same.
Now don’t get me wrong, neither are well balanced or smooth compared to todays reels but the 1000 is tighter and everything is moving with minimal play and it feels a really really good solid wobbly reel.
The 2600 and 1600 are still great they still feel like they’ll do the business but they are more sloppy in comparison and it’s not wear or an obvious thing that is wrong with them, I’m gonna say they just don’t meet the same accuracy between moving parts working with each other.
If the machining tolerances on the SS2600 we’re say 0.05mm and on the 1000 they were 0.02 I would never be able to see that but through gear trains and mechanical movement I might definitely be able to feel it and that’s what I believe is the difference.
