Resilient cruiser part 7

I have flipped the model over and resumed working on the top again.
I have been trying to finish the communications tower and I think it's done.
I sprayed some grey primer just to make sure.
The whole communication tower assembly has been made removable for safer transport in the future. It has a number of small and fragile antenna arrays.
It is held onto the model with a strong magnet near the front and a small lip that mates with a tab at the rear.

Thanks for looking.
More soon...
