Restoration (Automotive, Aeronautical & Railway)

Restoration projects are one way in which BNM can fulfill a role within the community although not all projects are local. They are however always unique and customers include industrial heritage groups, museums and individuals all with interesting stories to tell. Designs and thread fits are usually non-standard and a large amount of technical and material selection advice is required of us before an order can be placed.  In some cases, we are given parts to reverse engineer or provide mating parts for.
