What's that tool?

[twertsy]

So I inherited a bunch of tools from my grandfather. He worked for / retired from IR if it helps. This appears to be some sort of stabilizer / holder for maybe a lathe? I thought maybe a nurling tool but it has no wheels. Stampings on the handle are "ZEUS" and "DBGM." Any ideas?

looks like part of a nurling tool for a lathe. and zeus made them

That was my initial thought Roadglide but it has no nurling wheel(s). Maybe they broke off at some point....?
