Mike,
I think you have enough information to pretty well nail down that they are Crawford reels. I've mentioned that the refinements on your reels look to be something that were implemented over time and your reels look to be the latest versions. The lack of labeling on the tailplate cover of "Hawaiian Swordfish Reel" might be due to someone or a manufacturer breaking ties with Mr. Crawford. Friend Steve Vernon so kindly offered his assistance in doing some follow up research to assist, seeing the interest in your reels and the story behind them. He pointed out:
He (Crawford) applied for that 2nd reel patent in 1947, when he was in his mid-70s. Although I don't know the differences among the reels you've seen, I would theorize that if his later reels were based on his 2nd patent, he probably would have considered outsourcing their production, possibly to a company like Singer. The situation could have been similar to that of Frank Perez, who outsourced the manufacture of his reels after the war. Ergo, maybe the Singer folks should start their hunt in 1947 or so.
Steve mentions Singer because people I've talked to here who's families fished with Mr. Crawford informed me that he eventually had them produced by Singer, the sewing machine manufacturer. Which brings up maybe a coincidental point that you got the reels in an auction from Wisconsin, where Singer has been manufacturing for years.
I'll have to check the dimensions on my reel later tonight.
Anyway, verifying the manufacturer is one key sticking point that's kept me from writing an article for the Reel News for many, many years since Ed first told me about this reel. Mike, your find helps lean the needle more towards Singer so thanks for sharing your information. One other thing that I do need to point out is that Mr. Crawford came from Indiana to be the Postmaster for the new Lihue Post Office. After a few years, he became the manager of the new Bank of Hawaii branch that opened next door to the Post Office. He was a very prominent business and community figure on the Island of Kauai and, along with is wife, Mary, were well known in many aspects of Island life, particularly the fishing community. Unfortunately, they never had children, even though the prototype that Ed has photos of has a story of coming from a son or descendant in California.
