I might be able to help…but first need to make sure I have 2 crowns in order to keep a set back for myself!
Legs are 2nd. gen. versions & I am original owner (bought legs on their own (1993-4 I think) after getting RC 35s in 1992.
Shown here running 1/8” steerer - but can swap back to 1” + have uncut gen. Pace steerer. + shim that can include.
£343 1/8” + spare 1” steerers + vital shim to go in crown! inc. post costs
Image below shows them last in use 2019.
Can take some more detailed images if interested..
