Aquascutum of London Regent 100 Jacket Size 46

Aquascutum of London Regent 100 Collection mens blazer. Made in USA. The fabric is a grey and black check pattern with green and blue highlights. Fully lined with internal pockets. It is in excellent condition with no signs of wear I can see. There is no size tag - the space for this has not been filled in. Likely it was custom tailored. From the measurements, I believe it is size 46. Measurements: Chest: 47" Length: 34"
