If I can get the guy to reply to me I may do just that. I've already got half a bucket of duratex from the one I did in the spring and would like a second shot at the grill cloth. More so if they're not all junk replacement speakers I'd love to play a flatback and see what all the rage is. I've never seen one with black grill cloth and I'm not all that knowledgable on the history and if this is a desirable era.
If it's a flatback, it is desirable. Here are some pics including the front and back of the grille. The one you are looking at has a dolly. This is rare to find. The grille cloth is not original. It is available from Invalid Link Removed (I prefer this place, fliptops can short change you in that they can't cut along a straight line) or Fliptops Home of Parts for Ampeg Lovers.
