Mike,
Many will think that the gamebirds on that old Elsie are woodcock or Wilson Snipe. However, during the era that gun was made, shorebirds were popular and legal gamebirds in the northeast. Yellowlegs, knots, dowitchers, curlews (whimbrels), willets, peeps, plover etc. were all legal game. Some were longbilled, others shortbilled. Those birds look more like generic shorebirds, maybe yellowlegs, than woodcock to me. Great artifact of a bygone era. Thanks for posting. Gil
