Larsonguy,
I have a 57 Maple F20, it's a fantastic little guitar, much louder & articulate than any other F20 I've played. I love it. Best my memory serves, the maple laminate models were manufactured in 55, 56 & 57, changing in 58 to solid mahogany bodies. The early maple models generally fetch significantly higher prices.
They're not particualrly tough guitars, mine needed a lot of work: neck set, frets, bridge reglued, new bridgeplate & a lot of cosmetic work. Worth every penny & I'd do it again in a heartbeat. Mine has a narrow slim neck,
1 5/8 nut & short scale, neck feels sort of like a violin neck. Hard shell factory cases were rarely included with these little gems & are a bit difficult to find, somewhere in LTG archives are threads discussing new case availability from independent case mgrs.
Hope this helps.
Jeff
