“Androscoggin” is a simple pattern from Fletcher’s catalogues 1947-1955. It may appear in others as well, but that is the period I have. The recipe is as follows:
Body: claret floss
Rib: silver tinsel
Throat: white bucktail
Wing: green hackle
I’ve not found this pattern anywhere else. The only other lesser known patterns like the “G I Joe” and the “Sneaky Joe” that appear in the catalogues can be found in Stewart and Leeman, though it is worth noting that they were sold in casting sizes by Fletcher.
The catalogue pictured is c.1955.
