It is a monster and can really chew up details and time - but having said that when it's finished (which it never is) it will look great as the center piece of a room. I mean it will be the center piece as it is so large.
I bought mine in 1974 for $60 at the local hobby shop. Had to have it cause it was so darn big. Bigger is better - right.
Over time it has gone through several rebuilds - added r/c (front turrets turn in tandem with microswitches to limit travel in either direction) several years ago. I used the included motor and ran a single prop down through the centerline with a flex link and a stuffing box. It ran like a ski boat till I trimmed the nylon prop down - now it runs at a nice scale speed. I use a 6 volt gel cell for all power.
A few years later I replaced the deck with a scribed wood deck - that eventually warped from the water - then I went to a scribed plastic deck. I have also added the GMM etch set - only the first one - it is great. I had to cast extra 25mm AA turrets for the deck edge and make other mods to replicate the ship for its last sortie.
I have some pics on the modelwarship.com website:

Sorry - these pics are rather old - I have submitted newer ones last week.
