Can anyone Help me identify this guitar?

I purchased this from a yard sale. I could tell it had been in the case for many years. I have done an exhaustive search for another like it and have come up with nothing. It has no stamp anywhere, even on the block. The inlay is unusual, the seam is black. The back is one solid piece. I would like to find out the make and model #. If anyone can point me in the right direction or is familiar with this model, I would really appreciate all the info I can acquire.
Thanx,
Bill
