Here's one you don't see too often....

Interesting - looks to be more or less complete, even if there are quite a few bits of other kits in there!
How much is this kit generally worth, in "unstarted" condition?

I recently bought a similar "scrap" Sea Witch model (arrived in the post today) however it's the Aurora kit rather than the Marx one, and cost me about £6 including postage, not $75!  Similarly, it's a mostly-built and painted model which is distinctly battered, broken and faded, but appears to be complete, and the box included various other bits such as a few Revell 1/96 crew figures and some parts of other kit boxes.
I hopefully plan to start work on restoring this model fairly soon. Other than the injection-moulded sails, it looks like a fairly good kit. Like the Marx/Lindberg kit, it's about 2' long, around 1/96 or 1/100 scale.

   Yeah, that was the box! I still have that hull, and some of the deckhouses. Lindberg has this kit now. the deck is plastic instead of the old printed sheet metal. The box had to be big, because the hull is a one piece, 1/96 scale, 24 inches long.

Old aint the word, but there are a couple peaces to the uss arizona in there too.

 I tried it says the posting is unavailable?

You'll have to copy and paste it into the address bar. 

That model is old school.  I'm curious as to what the inside of the box looks like.
