Don't have much info but TMK they were produced for the tourist souvenir trade in the '50s/60s - my uncle was from Valencia and he brought one back for my cousin to learn on (she never did, BTW). If it's still structurally tight it could be a good grab-&-go/living-room beater, but I wouldn't invest any kind of real bucks for restoration/repair (got a couple cracks in the photos)...
FWIW the guy who was hawking these must have been
extremely popular with the
senoritas - the name loosely translates as "Joe More-&-More",,,
