unused Explore Scientific 127mm F7.5 APO multi-coated triplets mounted in aluminum push-pull lens cell ready to go into your refractor project. I bought it for a giant binoculars project but decided that the focal length is a bit too long. I would go for something like Televue's F5.3 objectives if I can find them.
$500 obo.
I also have a number of focusers suitable for this objective. I also have unused aluminum tubing you can machine to make it fit the lens cell.
