47 - I believe Snyders actually makes the aluminum two-blade fan. Tam's says they are out of stock until October, other vendors simply say "out of stock". If you want one you might contact your favorite vendor and see if you can get on a waiting list. I did that a couple of years ago when those fans were similarly out of stock. As soon as Bert's got an order in they shipped me two per my standing request.
