These items came from a local liquidation company and are new old stock. The company specialized in making signs of all kinds.
These ballast are fixed in a white bracket fitting but could be removed with relative ease if you so desire.
As far as condition the ballast themselves appear fine with a minor amount of dust from being stored.
The bracket fittings also show some dust and some rather heavy scratching if that is important to you.
