Here's a great write up on the state of play with the three, yes
three Mosquito projects underway with Glyn and AvSpecs.

Its pretty well known that a US based Mossie is at AvSpecs to get a new wing to mate to the original fuse under resto, but it now seems as though a new fuse is in order too.
Who could the other un named collector be. US based? Apparantly the reason the UK deal to purchase Glyn's one fell through was due to issues with getting registration, owing to the new build status of the structure, since it wasn't inspected at various stages by the UK regulatory body during build.
If They can inspect during build, they have better grounds on which to award certification.
