Correct!
Hurricane got into production so quickly because it used existing tooling a skills to build a slightly-improved airframe. Factory workers only needed a few new jugs and minor retraining to build the next generation.
From WW1 to the end of WW2, Sopwith/Hawker only made a series of minor, incremental improvements.
Even the late-WW2 Hawker Tempest retained a metal, tubular center-fuselage, load-bearing structure that was conceptually the same as the wire-brace wooden sticks used during WW1 Soowith Baby, Pup, Camel, Snipe, Triplane, Dolphin, etc.
The post-WW2 Hawker Sea Fury was the first to use a sheet-aluminum, stressed-skin, center fuselage!
OTOH Supermarine’s radically new, stressed-skin, all aluminum Spitfire required radically new tooling and skills. Just learning how to form compound-curved leading edges delayed production by many months!
