I broke out my Thompson Wing Former (quill wings) that I bought in the 70's or so. Old glue had hardened, thinner had evaporated.... I'm forming wings for old style quill winged wet flies in sizes 10-14. You put duck primary feathers in the jig, add the appropriate spacer, and glue the butts of the wings for ease of handling (and pairing up). The Thompson box is old enough to not have a zip code on it.
