NOS Wagner Headlamps ?

[Ironhorse]

Recently got these in a parts deal and have no idea of the value? NOS Tung-Sol headlamps in sealed cardboard boxes from the Wagner Electronics Co. Boxes are marked " U-64", not sure if that is a date code or what? I'm thinking maybe mid to late 60's or early '70 just from the colors and logo on the boxes. Have two 4002 low beam and one 4001 high beam headlamp. Boxes are in nice shape, no damaged edges but a few minor pin holes, most likely from ?? Gotta' be for the GMC 4-eyes crowd as the boxes measure 5'' x 5'' square. Great to set on the shelf in the shop/man-cave just for the nostalgia look.
