2 x Istar 127mm f5.5 lenses + binoscope materials

I have abandoned my binoscope project due to changes in interests. I am selling the parts which includes:

2 x Istar optical 127mm f5.5 achromatic doublets in cells
2 x 68mm secondary mirrors from Bintel
2 x mirror holders from the US - can't remember the supplier

Images show what's included. If I were to assemble this again, I would simply build a "binobox" as done on this thread on CN:

Everything is in great shape, with clean optics.

$1000 for the lot, including the other parts (aluminium tubes etc) in the images which are from my build.
(You would also need diagonals to complete the build if you were to copy the design in the link above)
