NMM 10862.  Guitar by S. L. Mossman Guitars, Winfield, Kansas, 1977

In the mid-1960s, the folk music boom resulted in an increased demand for acoustic instruments. Stuart Mossman, who had begun making guitars in 1965, expanded his business in order to capitalize on the market demand that he saw for acoustic guitars made to high standards of craftsmanship from excellent materials, while remaining very competitive in price. A flatpicker himself, Mossman concentrated on instruments useful to that style of playing, including high-end dreadnoughts. After a fire in 1975, Mossman had to reassemble a collection of fine tonewoods, but the company’s stock of Brazilian rosewood could not be replaced, resulting in a switch to East Indian rosewood.

NMM 10862, a top-of-the-line Golden Era model, features sumptuous abalone inlay on the body as well as the classic "tree-of-life" inlay on the fretboard. Every worker who helped build the instrument has initialed the label, in the Mossman tradition. The instrument was won in 1977 by Mark O’Connor, the celebrated fiddler and flatpicker, as the National Flatpicking Champion. O’Connor has been well-known in recent years for his own compositions and cross-genre collaborations with other famous artists, such as Yo-Yo Ma and Nadja Salerno-Sonnenberg.
