Last half of the first paragraph talks about the RFQs and makers:
". . . Ultimately Goodyear manufactured 9 envelopes, Goodrich made 5 and Curtiss assembled the gondolas for all of those 14 ships. Connecticut Aircraft contracted with U.S. Rubber for its two envelopes and with Pigeon Fraser for its gondolas. The Curtiss-built gondolas used by Goodyear and Goodrich used modified Curtiss JN-4 fuselages powered by Curtiss OXX engines. The Connecticut Aircraft blimps were powered by Hall-Scott engines. . ."
