It looks like some kind of drilling or assembly jig .
Most welding or silver soldering jigs are not usually as well made .
Maybe some one will recognize it.
If not, perhaps seeing some of your other unknown parts with it or knowing what type of industry your grandfather worked in would give some clues as to what it is .

Off the top of my head I'd say it was a user made indicator base of some variety, probably out of some spare parts sitting around. Could very well be an assembly or Drilling jig as Jim Christie suggested though.

The tools in the second picture would suggest to me that you grandfather was doing more tool and fixture making than general machining .
There looks to me to be a base and other parts of a surface gage among the angle plates and V blocks .

SWAG regarding the tool in the OP: The vee-shaped clamping jaws on the left hold a tool, probably a diamond wheel dresser. My guess is that it's part of an arrangement to dress grinding wheels, possibly to a radius.

Jonathon: If I had to speculate, I would say that your Grandfather did a lot of precision grinder work. Probably a toolmaker.

Not sure what the fixture is for, most likely grinding of some kind judging by the nice selection of tool makers tools here.

Those are nesting parallels, the slotted feet allow them to be moved together or apart and maintain stability. There may be a better name for them, but that's their function.

They are tall parallels. The "teeth" allow the parallesl to be placed close together with the teeth intermeshing. It also provides a wide base for stability.

Please consider that it might be a gesture of respect for your grandfather to display these items more carefully arranged than the jumble in your photograph.

The top view of those tools makes them look like a piled mess while in fact are laid out on a table...

And here I was thinking they'd been glued to the wall like a mosaic...
