National Duolian 1932

Final update: 

I've lowered the price of the guitar with case to $2000, shipping included. 

UPDATE: 

Thanks for all the attention on my guitar. I have updated the listing with items below:

• Guitar does not have a serial number stamped on the top of the headstock. I have seen two other Duolians of the same vintage, one had one, the other didn't. It does have the stamped National Duolian stamp on the face of the headstock, which began in 1931. 
• Action at the 12th fret is 5/32s. I have had no problems with intonation or tuning, but I've only played slide on it. 
• I have never taken the guitar apart, and it's had no repairs during the time I have owned it. 
• I'm not interesting in trades as I am paring down my collection. 

Please feel free to ask any further questions you might have. I have lowered the price another $100, which I feel is a good price for a great blues machine - maybe not collector grade, but the price reflects this. 

thanks!
