I have for sale an original Horrocks-Ibbotson card of 5 Blue Dun No. 10 Special Divided Wing trout flies. These are in great shape considering the age; they would be a great addition to any vintage fly collection. While they do not appear to have been used (no hook rust), the wing feathers are missing from 3 of 5 of these, and partially missing from the other two (see photos). This will be protectively packaged and shipped USPS Ground Advantage with tracking number provided. Thanks for looking, happy collecting to you!
