Collection de Alan Larsen, Etats-Unis

Vous pourrez trouver ci-dessous la collection d'appareils de Alan Larsen I collect early 1920 wireless radios. I have a fairly extensive collection of early 1920's American broadcast receivers. Makers such as Crosley, Atwater Kent, Grebe and Tri-City comprise the bulk of my collection. I also have quite a few rare makers sets. Thanks, Alan
