Love the Klusman progression Jay, love the Kansas City collection Rob (especially the Pete Conway cabinet).
Figure I should contribute. I gave up on collecting WA long ago, sold and traded away what few I had. The examples I now have typically came as part of package deal while trying to obtain a Detroit card. I only have one Fb, all the rest being Fc (not surprising). I'll also post the Fa vs Fb vs Fc cheat sheet that I previously shared to help those that might be scratching their heads.
