Thread: Rooney Butterscotch Score. Some Advice, Please.

Hi guys. I picked up what appears to be an old Rooney brush. It has a partial Rooney sticker that looks like it came loose and slipped down the handle a bit. It has good weight, and is IMO a high quality, lathe turned handle, every bit the quality of the handle on my Duke 2. I believe it to be genuine.
The glue bump at the base measures 22.44mm, and guesstimates with my caliper put the knot opening at Approximately 1mm larger.
It has turned a nice butterscotch over time. I know enough not to try polishing it out with polishing compound, thus ruining that butterscotch goodness, so I will soak it in hot tap water and some Dawn, and clean it well with a nice, soft cloth.
Here are a few pictures.




But, now to the 6 million dollar question, how do I remove the knot?
By this I mean that I plan to drill it out. But, from the weight of this handle I assume it is solid. In other words, I believe the floor that the knot rests on is solid, and most likely has not hollow area underneath.
How would I know when to stop drilling? I have done a few restores, but nothing like this brush handle.
I would greatly appreciate advise from anyone who has done a restore on Rooney, Simpson, any type of vintage handle similar to this. Also, any information on what model this is would also be appreciated.
