New Old Stock Shimano DX hub from the 1980's. We got these in a box without packaging so there are marks on it, but it is new and have never been built onto a wheel. 

Raw silver so could be cleaned/polished up nicely. 

3/8" 10mm axle. 100mm OLD. 

36H. 

Original Shimano track nutes included. 

Loose ball bearings, so could do with adjustment and would benefit from new grease. 

Circa 1981. 

Can be built into a wheel for you.
