#348-2 Mini-Wheel Model Maker, I'll post pictures on Flickr later of the box, instructions, and parts (once I receive it). From the on-line pictures, it looks to be in good shape.
A few months ago, I won an auction for a #371 Motorized Truck Set. The box was in great shape for being over 40+ years old... I don't have a deep seeded need to start collecting LEGO sets from the 70's, but the motorized truck was a little bit of a personal vindication for me. The Mini-Wheel Car and Truck Set was just going for too cheap, IMO.
The other ancient LEGO set I manage to pick up was the #725 Town-Plan in excellent shape. Not all the parts were there... I think the trees and cars were missing, but everything else was in great shape -- the bricks were still minty fresh.
One of these days, I'll probably pass them on to fellow collector or the LEGO museum.
