Well from the diagram H is closing your clasp nuts for threading, and I'd imagine G1 &2 are engaging forward and reverse clutches
1 is engaging cross feed and 2 is engaging long feed
You have three shafts through the saddle. Top one is the lead screw and should only be used when threading.. Next down will have a keyway along it and is your feed shaft for sliding and surfacing (long feed and cross feed). Bottom one is almost certainly either on a pair of forward / reverse clutches, conceivably it could operate on a motor reverser.
Why not get in touch with Tony Griffiths at lathes.co.uk and buy a manual ?
