Cute toolpost :)
I'll pass on the turret, it does look like Sparrey's but no idea whether they were ever made commercially!
The reamer either adjusts with the collar (pushing the blades along "ramped" slots to increase the diameter) or is fixed with inserted blades - first thing is to clean, dismantle, lubricate and reassemble, see whether the slots are parallel or ramped?
The bolts and tees are probably production stops to fit to a machine to limit travel, bolt them to the carriage / table or whatever and adjust the through-stud and locknut so when you're to the required dimension they hit something (e.g. bolt them to the lathe saddle, where the cross-slide (or a block attached to it) will run up against them when turning an outside diameter or boring inside) - useful when you have multiple identical parts to make, or to set up so the apprentice can make 'em without requiring skills ;) Often they bolt to a T-nut in a T-slot, along the front of a mill table's a common sight.
