I agree the SIZE of the older ones is really nice, but with the black faceplates, IMO, the black ones look nicer.
As far as getting them from Randall, have you tried calling them and asking them how much? I know their prices for the Chicken Head knobs are totally stupid. I bought 16 genuine "Daka Ware" brand chicken head knobs off eBay, just like the ones Randall uses for like two bucks a piece. If I recall, I think Randall was charging something like 10 or 12 bucks each.
On the other hand, there was one time a few years ago that I replaced my silver faces with black faces and got the black screws to replace the sliver ones, seems like they were either really cheap or they sent them for free with the faceplates when I ordered them. Roszatycki, I think it would at least be worth a call to customer service to at least find out what they cost.
