Yes it is a Saddleman Travelcade seat, model Desperado
I know cause I have one and like it! It is discontinued but I think JC Whitney may have covers available yet.
It's funny, I've also lost two of the stids on mine in almost the same place. I figure mine was due to where I strapped my bags to the sissy bar and back cause that is exactly where the straps came across.
If this is the same one I saw on Ebay, and the pictures look familar.. then it also has the gel seat, which mine doesn't. I've done an Iron Butt with mine so it is definitely comfortable for me.
