Rush 250A tool Grinder manual

Does anyone have a manual for this machine?
I've found 5 pages online about drill grinding, but I'm looking more for instructions on tool grinding (reamers, countersink etc.)

We used to have a Brierley drill grinder. I think Rush and Brierley were identical in operation. We used ours to grind drill points. For our taps and reamers we typically used Royal Oak or Hybco form relief grinders. We also had Oliver-600 and Giddings & Lewis HC drill grinders in a screw machine operation.

You might check to see if you can locate a Brierley manual. Operations for manual machine models were the same...CNC and automatic feed may have been different. Capacity was pretty much the only difference.

Attached are a few youtube videos that show the grinders in operation.

EDIT::::::
NOT SURE WHY YOUTUBE LINKS DO NOT LOAD>
Do search on youtube a nd type in the following...
Endmill & Counterbore End Grinding

Video with one of the grinders showing endmill operation should load and give you some info. Sorry about the bad links, but if you search around enough on youtube you can find info on Rush/Brierley/Pippien machines.
