Looking at duplicate kits I still have in the stash - here is one that I really enjoyed years ago for sale unbuilt to just the 50 U.S. states this time. (beyond the 50 U S states, I have in the past mailed to a U S address and the buyer picked up at that location or had package mailed to him/her.)

My unbuilt unopened Destroyer Benson Dragon 1032 kit box is like new with no dents, cave-ins or bumped corners. Box art provides a complete display of the kit parts with CAD images of the kit. Still factory shrink-wrapped and never opened.
Kit is still factory-fresh and mint: Parts for early war and late war build and six different scale figures crewmen. Main deck is cambered and hull part has excellent shaping overall in two pieces: upper for waterline finish and lower can be added for full hull. All armaments are as good as I've seen. Brass etch included in kit.
$42.00 plus postage. Payment will be made by mailing a US $ USPS Money order.

Email me with questions and I will email you pictures of this never opened kit = fleetsin AT hotmail DOT com   I will need your mailing address to get your package shipping cost. And you can tell me if you prefer USPS or UPS. No hidden costs.
If you can pickup here north of Denver, CO there is no shipping cost. Or if you live in my area I can drive to meet you within 50 miles of my residence and there is no shipping cost.
We can discuss when you email me.

Thanks for looking.
