Not sure if this is an original jacket, so I have priced it accordingly. But it really looks original has all the original hallmarks, such as the full length TALON brand zipper and decent wool lining. I bought these together with the tanker bib trousers that you can see in the list of items. Both go together really well on a mannequin.
The condition of the outer cotton fabric is excellent throughout. The wool liner is good and has some small mothing and period repairs. The collar and cuffs have some discoloration and mothing, as can be seen in the photos.

The size is unmarked, but fits me well at 1m80 and 75kg, with some extra room.
