Rooting through the stuff in an old engineer's toolchest the missus bought me I found this -can anyone tell me what it is? Robin.

It may be a 'vertical stand' for a ruler.

[a better indication of size might help]

Hi Michael
Its a base for for a Caliper so you can use it as a height gauge

Thanks, Nobby

That makes perfect sense, now we know the size. … I had originally estimated it at only about two inches long [mentally 'scaled' from the knurling on the screw]

Thanks for the explanation Nobby – still not sure how it would work tho unless one ground down the fixed jaw so the moving jaw has some overhang?

OK folks. It looks like one of the gadgets sold for sharpening wood saws. I have seen something similar, but woodworking isn't my cup of tea. The round bobbin goodie, which is double ended, is pressed by the knurled screw on the side to hold the saw blade with the teeth pointing upwards. The base was normally cast iron so it it doesn't tend to move around on the bench. The slot is wider than a handsaw because it could also be used for tenon saws which have the thicker spine of a folded over piece of channel section crimped onto the blade. I wonder if there is a makers name somewhere to confirm this ?
