There is a 3 year guarantee on restorations. On some rare radios, we make new replacement parts for the more difficult to find pieces, such as 1938 Buick dial gears, 1940 Cadillac push buttons and thumb wheels, Ford tuning shafts and other specialty items. We have a small, fully-equipped machine shop that enables us to make some hard to find items.
