water key on 2nd slide

[RickF]

I've seen 2nd valve slides with amado water key, but never a standard water key. Joe Sellmansberger (aka 'Bloke') shared pictures of his Willson 2900 he has up for sale showing that slide with the water key. Interesting as the pull ring shares the mount for key and spring.

The pull is attached to the moving key, which would concern me a little, mechanically. That's not where I would want to put the stress (especially if the 2nd slide sticks a bit). But I'm not sure how else one could do this in a non-clunky way
