This is the Spindrift Model Kit put out by Marco's Miniatures.
All pieces seem to be present, unassembled and bags are still
stapled shut. Comes with instructions and limited edition
card. This kit is #58 out of 500, and were made in 1990.
In 10 years of collecting Irwin Allen items, this is the first
time I've seen this kit. This was up on eBay on 9/24/06.
