Charles, I thought I might have an extra, but don't.
If your Hoehn top is the style with the alum. 'L' side plates, the bag from Sinclair's RT2510 top works as a replacement. I know, 'cuz that's what I have on my 3" Hoehn top. Sinclair lists the mfg. as Edgewood, but they must be a Sinclair exclusive as they're not in the Edgewood catalog. The Sinclair replacement is leather on one side and Cordura on the other...kind of slick (pun intended). I believe I had to punch new holes in the bag for the hold down plates.
I got a PM from a gentleman in Arizona who was willing to make one; I don't know if there are enough of us old Hohen top users to make it worth his while -- probably not, or Ron would carry them.
