Meade 1.25" 45 degree Erect Image Diagonal Prism #928 - 07217
In original box, no caps or covers, missing the set screw to hold eyepieces in the barrel. Does not affect usage, other than you must be careful not to let the eyepiece slip out.
This was a display item that I have from my old astronomy store inventory. Stored away inside a zip lock bag to keep dust off when we removed it from the sales floor.
