Hello, I have a men's outdoor sporting vest with a Howard Flint Flintwear label. The only information I've been able to find on the internet about Howard Flint and Flintwear is a 1950's ad. According to the ad, Howard Flint Ltd supplied many famous people with their Flintwear sportswear clothing, including Amelia Earheart, members of British royalty, and British olympians. Does anyone have any information on this label and what something like this could be worth? Thank you.
