I will shortly be trying to convert my Atlas 10F manual gear change lathe to QC gearbox(I think). My lathe has a reversing mechanism mounted on the left end of the leadscrew, so I will have to remove it and adapt a reverse tumbler up by the headstock. Rex Burkheimer of this group, has been very helpful with info about this conversion, but the only mystery left is the shape and location of the subject part, which was (apparently) offered in the QC conversion kits offered for my model of lathe many years ago (but no more). The part I need is the "Tumbler reverse quadrant plate". It bolts onto the left side of the headstock and provides the proper pivot point for the tumbler assembly. It also has the detents and labeling for the tumbler position. If you have one, I'd like pix or is it's for sale, I'll buy it. If you have any info about it, I'd appreciate that, too.
