There's another member selling louvers for here on $100 and I'm waiting to hear back on if they've gone yet, but they've been up for a few weeks now.
Also, with the whaletail, you might want to post much better pictures and specify whether it's an original or a reproduction. The condition is really key to what you can charge for those these days.
Three years ago, $200 would have been a steal for either. These days, tough to say.
