I'm pretty sure this is a dovetail chisel, but I can't find anything like it by google.

It was badly eaten by rust, and I only worked on it because it was my grandfather's.

The ferrule was rotted off, and the handle came away easily. Because of the handle it looks to me like it was made as a paring chisel. Is this what it is?
Can this chisel be used for chopping? - if I put a different handle on it? Or is it designed specifically for paring alone? What angle is appropriate for this chisel?

Anybody have an idea who made the chisel? - any brand name rusted away years ago. It's probably European, it spent the last 50 years in a shed in Ireland, about the dampest place on earth.
