Needing some Bristol Spline wrenches/drivers

[zjrog]

I only want to spend the money once. I don't need a huge set, but I need a bunch of the smallest sizes. Either my search fu is off or I will be mostly stuck with XCelite (Not that I mind, I just am not fond of the packaging). I had a smaller set once, short handles, that I seem to have misplaced in multiple moves through the years. I am working on some older lenses that use the smaller Bristol splines. Maybe Wera or Wiha?

Bristol is still in business, and still manufactures Bristol spline wrenches and screwdrivers. They also manufacture high quality hex wrenches and Bristol spline screws. I suspect some USA tool companies just source their Bristol spline screwdrivers and wrenches from Bristol rather thsn making them themselves. If you check ebay their are multiple sellers selling various sets.

Curious - where are these fasteners typically used? I've never seen them.

Snap-on still sells the L style keys.
They offer a set or individual keys.
With their free shipping and warranty, its hard to beat.

They used to be in some cell phones, but I'm not sure of anywhere else they are commonly used

I'm clueless, but the Bristol Website indicates
http://bristolwrench.com/bristol-wrench-spline-drive-parts-list/
"avionics, instruments, radios, aircraft maintenance, printing and engraving"

http://bristolwrench.com/about-bristol-wrench/
"electro-mechanical instruments. They required screws and wrenches that could stand up to industrial environments, vibrations, and frequent removal and resetting."

Never seen them but they look a lot better than a standard Allen head. Any real world experience?

They were used extensively in IBM Selectric typewriters (the ones with the rotating ball). I have a set of Bristol wrenches in a pouch with an IBM part number on it.
