I just boucht a Classic OS C/R on ebay for 127 USD. It has a brown chord bar cover but no label. The paperwork that came with it included three price lists from OS dated 1980 to 1982. It is very clean and after cleaning it up and replacing two missing strings it sounds pretty good. The more I play it the more it opens up and the better it sounds. I don't know if the back and top is solid or lainated but I think they might be solid wood and it may have been made in the USA. One day soon I am going to replace the strings and one or two chord bars that I don't use but for now it sounds OK and really stays in tune. I don't have a problem tuning it with the T wrence and an electronic tuner. I doesn't have fine tuners. I play the fiddle and Uke and tuning is not anything new to me. I would like to know it this is an early 1980's harp. When did OS send the manufacturing over seas. I know ukes and mandolins went from here to Japan to Korea and now is done in China. Some of those are realy great.
