Hello, I have for sale a 1.3" Astrosystems secondary holder. It has been a bit altered from original. The top plate that has the 4 set screws has been filed down a bit smaller on it's edges than when new, and also the round plastic piece that the diagonal shroud screws onto has been filed down to a smaller diameter, so there is a bit of a gap bewteen the shroud and the round plastic part (I was planning to use in an unshrouded 1" diagonal design). Otherwise it still works. Cost: $15 shipped.
