Winsor & Newton Winton Vintage Drafting Instrument Set Made in England

Description

Up for auction is a vintage Winsor & Newton drafting instruments set complete in original folio pack.
This set looks very nearly complete and consists of a very wide variety of instruments for all manner of drafting and technical drawing tasks.  Even has an original pencil lead in the case.
I had no idea that Winsor and Newton made drafting instruments, but obviously they did, but it is difficult to find when they were in production.  My guess, based on the materials used and similar items is that this was some time in the 1930s or 1940s.  It is entirely possible they are older than that, but I simply have no idea.  If you have some expertise you wish to share, I would love to hear about it.
The set is being sold as-shown, and as it is a vintage item it is a final sale, so please inspect the pictures carefully and feel free to ask any questions you might have.
