684sm liner compatibility between sizes
Hi, I've found an almost new 684sm, unfortunately without liner and collar.
I know they are not available as spare, so maybe I can search an used 684 with a good liner and collar.
My question, maybe silly, is... Only a size 40 liner/collar can fit on a size 40 684SM or also the 38 (or 42) can fit?
The liner are all different from size to size?
