Boxford Fixed and Travelling Steadies and a spindle-nose thread tap. to suit Boxford AUD, BUD, CUD, TUD, Model A, Model B, Model C or others with a 4.5-inch centre height. 
May also fit other Southbend clones.  Also, a top-quality Warrior brand 1.5" x 8 t.p.i. tap to suit the spindle nose threads on these lathes.
The steadies are complete with ‘fingers’ - but the fixed steady lacks the plate and securing bolt that locks it to the bed but not difficult to make from a bit of flat bar, either threaded to suit a long bolt, or else just use a piece of studding and two nuts and washers. There are two studs, nuts and washers to mount the travelling steady to the carriage, but the threads on these are bit ‘drunken’, so you might want to find some BSW bolts to make for a ‘proper job’. £170 for the pair, including post.
The tap looks as-new as I’ve only used it three times to clean out threads in Boxford backplates. No markings as to whether this is HSS or carbon steel, but it’s branded Warrior, so you won’t be taking a chance as to to quality. Useful to have around, as some Boxford – and other 1.5"” x 8 t.p.i. backplates on sale today can have threads that are tight on the spindle. £60 including post.
