flux remover for sale, brand-new and used.

I bought this unit at auction about 7 years ago with the intention of using it in the repair of my Model T Ford engine, but have not once used it. The paperwork with it is all dated 1996 so I’m unsure if any of the chemicals are still good or not, but here is a list of what is there: Box 1: Magna-Flux NDT Spot-Checker black light unit #ZB-100 and paperwork in original fitted hard case.
