Vintage Martin style 1-C Concert ukulele. It's all original and in excellent condition except for that line in the middle picture, I feel that is just in the finish but could be wrong, it doesn't look like a crack to me, price is reduced because of it, book price is $1200-1500. It has no affect on the playing. Also the leather straps or hinges that hold the top on the case are broken.Shipping is $30 anywhere in Continental USA. Not sure of age but would quess  1950's.
