Martin F-1 Archtop - Spruce/Mahogany (1940)Now here is a special, rare and unique instrument, just in for consignment sale. This is a Martin F 1 Archtop guitar, in wonderful condition! Martin had a brief history of building archtop guitars from the early 1930's through 1942. They stopped building archtops during WWII, and never re started after the war. Their F sized archtops were larger (16" lower bout), fancier and to most collectors, more desirable than their earlier and smaller "C" and "R"
