Tommy Wonder, as I understand it, made his own take-up reel. It was based on the Martin/Hammerton design. He modified the design to suit his needs, machinery at hand, and skills. Drawings to illustrate his version are in The Books of Wonder (volume 2). These are drawings not really plans; but enough info is there to build your own. I've been playing with take-up reel design again for the past two years. Each maker seems to experiment with the design. On such items there must always be decisions concerning things such as metal alloys to be used, spring thickness/width/length, bullet size/shape, type of cording, arm connections, cord guides, lock type, etc.
Martin's background in watch/clock making is very evident when the insides of a take-up reel are studied.
BTW The reels show up on auctions. The past two Martinka auctions each had a reel.
