The is a jacket from the estate of Peter Wyngarde bought from a specialist auction of his estate years ago - the jacket is Lincoln green with short collar - three button with a label M Berman on the inside and noted Peter wyngarde in the inside of the inside pocket label (see scans). No idea when this jacket was used. It looks similar to the one in a touch of brimstone episode of the Avengers (but it isn’t!). It is very dapper dandy and so typical fashion he wore in The sixties! Very Peter!! Hopefully it was from on e of his productions but research needed. The condition is great for its age but not perfect. See the scans - I’ve tried to highlight all areas for you.
