I was looking on the Tower Models site recently and noticed that in their section for Gladiator Models this kit is now listed although still 'to be announced'.
Unfortunately the Gladiator Models site is down at the moment so no cross-referencing is possible.
As a 'J9/10' is proposed (that is GC classes 9B/9D/9E/9H) some interesting variations may be possible, as discussed in my earlier post. Anyone with a GC or CLC layout is going to be able to justify at least one of these, and really I think three or four would be more the thing.
I'm looking forward to this becoming available!
