This is a pristine example of Irvin Air Chute's 1939 contract electrically wired Irvin in a decent size 5. Until recently I owned its bigger brother a size 6 from the same contract-B25526/39/C.I.B. This one retains its wiring harness, but the plugs were removed years ago. There is almost no wear to the fleece and it has seen little service if any. The zips are brass single trunnion Dot made in Englands and the tan pulls are original to the jacket. It has had no re-stitching to the seam tapes or belt and the fleece is extremely supple and strong with no issues whatsoever.
