Thought I'd go through the cupboard and do some show and tell

First up, the Stanley No. 30 angle divider. I guess this is the precursor to the Festool Symmetric mitre saw for when you need to find the bisector of an angle.

Marks on the back for common shapes

The hole in the cross bar is bored slightly off centre to the threaded hole, so the taper on the screw pulls it hard up to the reference edge on the main stock

Next we have the Starrett 49 combination bevel. It's quite a versatile little tool and the various angles can be butted up to the straight edges or each other to create a variety of different try squares

Finally one of my favourites, a Scholl's patent 4-post rosewood marking gauge with a dovetailed brass slider on one post for mortices.

You'd think it'd be a right pain to set, but all 4 beams somehow manage to stay completely independent so you can just go around and set them one at a time.
