The time frame corresponds with Bf 109 G-10 “Black 2” W.Nr. 610824, now in the USAF Museum. During this restoration attempt by John Caler, the skins were cut up and sold as souveniers to raise money.
The story of this airframe is chronicled in Jerry Crandall’s book “Yellow 10”, Eagle Files #2. According to the book, then-owner Bud Weaver received a telephone call to alert him that the aircraft was being hauled away by a junkman. The fuselage was saved, but the wings were lost. The book does not mention a “Gruppe 109” organization, however.
