I'm kinda new at this collecting thing, only being at it for a couple of years, so I'll go first.
The reasons you brought up are all correct to some degree. It's because of Fred and the contributions he made to archery, and it's because of the abundance. Even the rarest bows pop up occasionally.
It's also because of function, I don't buy vintage bows to hang on the wall either. If I own one it's been shot and will be shot again. Some of them, many many times again. I have no use for a dog that won't hunt. That's just me.
I realize the fleabay prices look huge but in many cases, but for a fraction of a new bow cost you can buy a Vintage bow that shoots as well as most modern bows. If they are sound, they are no more likely to break than bows built today. Any bow from any manufacturer could break.
There are many other bows that are collected such as Howatts, Wings, Howards, Pearsons etc, etc. All have their own faithful followers.
Bottom line for me is, I like bows, especially 1-piece recurves. If I have $300.00 to spend on a bow, I'd rather buy a bow that has a little history attached to it. A bow built with real wood and built by craftsman. If I choose to sell it someday, I'll likely get my investment back for it. If I spend that same $300.00 for a modern recurve I'm not going to get much and 6 months from now I'll have even less.
For a quick comparison, take a look at a late 60s Super Kodiak (currently selling for $200-$350)laying beside a 2008 model of the same bow(currently selling for $449). The craftsmanship and materials difference is like night and day. In 5 years the 68-69 SK will still be worth $200.00 to $350.00. Who knows what the 2008 SK will be worth, but I'm betting it will be less than $200.
