Just came across this thread while browsing. I have a Levin LS18 from 1964 which I bought about 15 years ago from a lady in her 90's. It is all still original and although looking its age has a beautiful sound. I mainly keep it strung with 13's and use it for playing in open tuning and for playing bottleneck as it has such a big sound. If my memory serves me right these Levins were often bought in the 6o's as Martins were either unavailable in the UK or too expensive for the average player. Although I say it is showing its age, the wood and the grain look wonderful.
