I have an extra Tantive IV CR-90 that I want to turn into the Archer, a CR-92a Assassian class Imperial ship piloted Ensign Nada'.

I'm really just going to repaint to look Imperial (cleaner paint job with navy blue scheme instead of red) and add 3 Turbo laser turrets and am going to remove the com dish (which I am going to use to replace the round com dish on an extra Falcon that I am using to update it for the look of the Falcon on The Force Awakens.)

Anyone know where to get the lasers?

Funny that ships is supposed to have six dual turbolaser turrets, to the CR90's two, but in all the photos that I've seen they show none.

If I were you I would check shapeways for turrets, and then contact the maker of the closest looking one, and ask them to modify the model to your specs and post it for sale.

Thank-you! I couldn't remember them for the life of me!
