The 1929 SL-1 was designed by Wallace “Chet” Cummings featuring a laminated plywood-clad, steel-tube, monocoque fuselage. Originally tried with 55hp Velie M-5, the price was $2,950.
The one prototype, NX470E c/n 1, received ATC 2-182 and at least five production models were as built as SL-2:
NC102V c/n 102, N460W c/n 106, N461W c/n 103, NC487N c/n 101, NC11950 c/n 105, maybe c/n 104.
The sport design failed to make it in a slumping market.
