I just bought this OS autoharp on ebay for my wife a few days ago and it arrived today. After opening it up, I was surprised that it was as old as it is. It is in absolute wonderful condition. The strings were loosened while it was in storage and retuning it, I could feel that it had been tuned on a C (higher strings) and G (lower strings) diatonic scale. The strings want to go back to their old tuning. I tuned it chromatically, but it will probably need a new set of strings (anyone know a place to get inexpensive strings?)
Anyway, it came with a booklet that has the date August 1, 1982 in it. So I know that it is at least 30 years old. No discernible wear, cracks, or rust at all. It all looks brand new and came with a sort of flimsy hard case. It onviously spent most of its life in the case. It also came with an extra felt bar and an E major button. I suppose they belong together.
Here is a link to the ebay listing:

I would really like to know what model it is. I know that it is a model C from the chord buttons, but nothing else. It looks like it might be maple, but I am not really good with woods other than those commonly found in hardwood floors. Any help identifying it would be much appreciated. I am thinking about getting a fine tuning set put on it.

Thanks,
Ryan
