Description

The photos are large. Hoover your mouse pointer over them for a detailed view.
Large assortment of gears. In the first photo Weldun gears in the package are shown at the top. Spur gears are at the bottom left, crown gears at the bottom right, pinions/smaller gears and set screws in the top two rows.
The Weldun gears:
24 - Weldun 64 pitch 58 tooth 1/8" set screw spur gears new in package
1 - Weldun 64 pitch 58 tooth 1/8" set screw spur gear used
5 - Weldun 64 pitch 58 tooth 1/8" threaded spur gears new in package
5 - Weldun 64 pitch 37 tooth 1/8" set screw spur gears new in package
1 - Weldun 64 pitch 37 tooth 1/8" set screw spur gear used
The rest of the gears: The vast majority if not all of them are new. Many with tarnish from age but unused.Of those that have set screws, most are missing their set screw. But there's about 40 or so flat head set screws included, which will still not be enough for all of them. Most spurs and crown gears are 1/8" set screw gears. Some spurs gears are threaded. Some of the pinions are 1/8" with set screws, some are .091" solder-on. Some are 16D size solder-on. Some pinions may not fit anything. And I'm not sure all of these gears were intended for slot cars. Years ago they were sold to me as slot car gears, but as I'm looking at them I wonder.
It's a lot of gears. I've described them to the best of my ability. Please look at the photos carefully and determine for yourself.
