I recently had Pendra of Tent Repair Services in Camden, Maine, make a heptawing similar to this one for my grandson to attach to his Little Dipper. Pendra worked at Moss for many years and then continued to repair Moss tents for REI after we sold that division of the company in 1994.
Tent Repair Services is a great resource for Moss tent owners. It has all the poles, grommets, fabrics, netting and other materials needed to make Moss and other tents as good as new. The company's specialities include tent and rainfly modifications, panel replacements, construction of replacement rainflies for many tent models, and a variety of custom work.
