Help ID'ing boring? tool

Hello,

I found this at the scrap yard:


I'm curious about what exactly it is, and if there's a chance I could use it with my 9" SB lathe. The shaft is 1.5" diameter. The cutters seem to be adjustable from about 3" to maybe 4" - I haven't taken it apart and cleaned the inside yet. The only visible marking is "Herbert" and looks like "BSAL". Might be from Herbert and Cridan in the UK as there is something similar on their site but pretty small and no other info I could find.

Thanks,

Gary Fuchs

Looks like a counter bore tool. For a turret lathe.

It's a combination centering and facing tool that was used on a capstan lathes for mass production work.

Thank you both, looks like I won't be using it though.
