There is Vintage Hunter......... But before you do anything, you must ask yourself if it's the pre-focussed-on-an-optical-bench-telescope that needs adjusting or your eyes by means of spectacles. MANY shooters simply will not accept that they might need spectacles! If it's the telescope, unscrew the 4 round or cheese head screws holding the PLATE, cover, segment in place. Under the cover, you'll see a small alloy or brass 'SEGMENT'. Hook this out and notice that underneath, it is toothed (in such a way that it can be used in half pitch mode by rotating it horizontally through 180 degrees). Under the segment is what looks like a threaded or splined ERECTOR CELL. Mount the telescope firmly and aimed at a distant aiming point (a DAP). With a small screwdriver, gently move the brass erector cell fore or aft until the image and the grat are perfectly focussed. When they are (if they're not ........... that's another problem.....!) note which way round the segment will align with the splines/threads on the erector cell. Put a small blob of graphite grease in the hole followed by the segment and screw the cover down.
Got that.........? I have done one or two of these. BDLalso sells a good readable book about these telescopes. Cheap too!
