About Vintage Martin Ukuleles: Martin Ukulele Models: Martin 0m, 1m, 2m, 3m, 0k, 1k, 2k, 3k, 5k Ukuleles were in highest production from 1916 to the 1930's, though still manufactured in quantity until 1965. Production quantities during some periods were as great as Martin guitars. Martin ukes are considered to be the best for craftsmenship and sound. The Koa wood models are more collectible than mahagony models. The fancier style 5 models are worth more than plainer styles 0 to 3. All sizes are collectible. The first Martin ukes, built in 1916, have serial numbers ranging from one to less than 200. Ukes made after 1916 do not have serial numbers and must be dated by specification changes. For example, in 1962 Martin added "made in usa" to the inside stamp. Ukes have the Martin stamp on the back of the peghead until 1935. Peghead decals do not appear in catalog photos till after WWII.
