Unusual very large sized late War Irvin. I have only seen one other from the same contract and this one had the early War two piece front and back. The Dot double trunnion zips are typical of earlier jackets. Perhaps made specially for a senior officer as most jackets at this time were multi-panelled. Despite the rapair and damage should do very well.
