Cox Black Widow .049 Engine w/ Wrenches, Glow Clip, Box, Great Condition

For auction I have a used, very good condition Cox Black Widow .049 . It was flown for a few seasons on an above wing pod on a Goldberg Gentle Lady glider. It is complete, and includes several Cox multi purpose engine wrenches, a glow clip for starting, a spare (used) glow head, an extra spinner that was shortened for use with thick hub propellers, a Thimble Drome 3 blade propeller, and an original box and instruction manual but the box does have a notch cut out of its closure flap.
The engine was oiled and stored on the shelf for many years inside in an air conditioned house, and has not been run since. The needle valve turns but feel gummy, so I expect that it will need disassembly and cleaning before it will run well. However it turns over smoothly and the cylinder isn't corroded looking so I am sure it will run well once cleaned.
