1930s 40s Derby Cap Co Umpire Referee Hat Wool Navy M 6 7/8–7 1/8 Wool 1940s

Authentic 1930s–1940s Derby Cap Co. umpire/referee hat, constructed from durable navy wool with classic early-mid-20th-century proportions. This style was commonly worn by baseball umpires and referees of the era, featuring a structured crown, short firm brim, and ventilated eyelets. Interior shows original Derby Cap Co. branding (Derby Cap Co. of Boston / Louisville, KY), with a leather sweatband and traditional taped seams. Size marked Medium, fitting approximately 6 7/8 – 7 1/8. Color is a deep navy wool, with visible natural wear consistent with age and use. This piece appears to come from the same era and likely the same owner as a similar derby cap, making it a great companion piece for collectors. Condition: Good vintage condition overall. Wool remains structurally solid with moth holes and staining seen in photos. Leather sweatband shows age-appropriate wear and patina. No major tears or structural damage noted.
