There are two period FG rear stands on ebay that fit the 851/888/Corsa rear swing arm. FG no longer sells this style/shape of stand with the squared off back. These are nice when displaying a bike, because they don't stick out far from the rear of the bike, and they are what the factory race team bikes used.
I already bought one, but there are two left:
