I have a Pgriff1 with the tubes, apertures and objectives for 300mm f 5.6, 400mm f 5.6, and 600mm f8. They are currently mounted with an adapter for Nikon, but the adapter can be changed and almost any mount can be had. The original lens has a 39mm (Leica) mount. I have added a 39 to 42 adapter, a 42 mm focusing helicoid (to adjust infinity on each lens) and a 42 to Nikon adapter. The optics are all very good (9+) and everything works as it should. I just don't use it anymore. I am asking $250 including shipping in a flat rate box for the whole thing. The picture is of the unit with the 400 mm mounted. Plenty more picture are available if interested. The second picture (of the moon) was taken with the 600mm.
If no further interest, I will remove this on Monday and go to eBay.
Thanks!
