Trying out the link-and-pin couplers on the coaches, I found the plastic pins a very tight fit, to the point where I would have to ream out the holes in the coupler bodies. All very well for a fixed rake, not so much when you have to uncouple for storage. So I decided to make pins from 1/16” brass wire that will double as hooks for three-link coupling chains as used on the rest of my stock.

As a hook. Height above rail (1” to coupler centre) matches my standard buffers/hooks.

Side view of the link. Closer coupling than three links. The brass pins fit nicely in their holes.
