TBH I would clean up the splined shaft and make a new bush if there was a lot of play, looks like it hasn't been regularly oild and swarf has been allowed to enter through the oilway. I am not seeing anything wrong with this machine that a bit of hand refitting wouldn't cure. Cross slides are always worn, especially the nut, ang gib strips can be checked for flatness, cleaned up and re adjusted, and V ways blued up and high spots removed quite easily. Takes a bit of time and patience. As you said, you are not making parts for NASA and all older lathes have wear, but can still make accurate parts. The accuracy comes from a good operator who knows his machine. Look on the score marks as oil reservoirs! Remember also that cutting puts downward pressure on the carriage unless you are using an inverted tool and running in reverse, so upward play on the carriage is not that important, and fairly easy to cure. I have just had a bit of a "go" at my Colchester Student, and it is definitely better for it, as I found loose parts in both gearboxes loose in the oil, and took quite a lot of play out of the slides, but it was more accurate than I am before I started on it! Getter done and make parts!
