Picture one shows the completed hinge formed in this case from stainless steel and copied from my Nippy, earlier hinges were made from Nickel silver. Adjacent to the pencil you can see the start of the mounting boss also made from stainless but still requiring the threaded portion attaching.

The second picture shows the various stages of forming a hinge section, some appear white because they still have the plastic protective film attached to the stainless sheet, on the right is a finished and polished hinge segment

The final picture shows the forming jig made to produce these hinge sections.
The bonnet panel has a return flange formed on its edge and the hinge sections are slid onto this, once full assembled the ends of this flange are bent back over the last hinge segment to hold everything in place, this is what Marks picture shows. If any of the above is unclear I will endeavour to take more pictures in order to clarify.
