I believe this is a 60s era Lee Storm Rider jacket with the lining carefully removed.

Brand - Lee

Content - Cotton

Size - approximately a modern Large but check measurements to ensure fit

Shoulders - 20" across

Chest - 24.25" pit to pit

Sleeves - 24.25" from shoulder seam

Waist - 21.25" across

Length - 24.75"

Condition - The biggest flaw is the missing lining but there are signs of wear throughout as pictured. It's still a great jacket that should last for many more years though.
