U.S. Sleeveless Sweater Marked With Laundry Number - Nice Used Condition

U.S. Sleeveless Sweater. Executed in knitted OD shade wool. This example is fitted with a commercial brand makers mark 'Paterson Knitting Mills' and marked with a partly washed out laundry number. No visible size markings yet I would estimate a size Small. In overall nice used condition.
