work?

Dave,

It's a hammer head boring jig. Clamped in a drill press vise, it holds a 
hammer head at an angle set by the gauge you see on the round part, and a rake 
adjusted by pivoting the little sticky-outy part (which is also where the hammer 
rests. 

The Renner head boring jig is more elegant, but I have drilled many many sets 
on one of the Brooks jigs. I use it for grand hammers, but I suppose you 
could use it for verticals by setting the travel of the drill press quill.
