Grab it. You could scavange the hardware and get $300.00 by selling it piece by piece. But don't do that. Get her and retore her and have fun with her.
Look for a hull ID stamped into the wood of the transom inside the boat, most often starboard side and sometimes stamped upside down. Also look for a rectangular metal builder's tag with manufacturer name and location and serial number. Serial number and hull ID are DIFFERENT. With both I can tell you what year she is.
Pull up the floor boards and look for rotten ribs especially where they butt up against the keelson. Look for a hook or hog in the hull from improper storage.

Glad to hear your getting her. Have no fear there's plenty of folks to help you through her restoration. Get a copy of "The Complete Wooden Runabout Restoration Guide by Don Dannenberg". It's like $25 and change on Amazon.com. Great book, it talks a lot about Chris Crafts but still applies to the majority of wooden runabouts.
Picked up the thompson yesterday. did some more looking at the ribs. looks like most of them have some rot. and the boat is not sitting on the trailer very well. the bunks are short and that is why the roller is pushing up the center of the boat. here are some photos of the underside.
