There has never been much care with spelling in any of these catalogs...
One must simply gauge for one's self.

Yep - and, it works - just buy it.

The Kontaktor model I have was made by Correx.

Kosher?  Smosher!  It's all tref!  

If there is a reason to get anal about which center pins to use on S&S
instruments,
it is because the ones you get from them are tumble polished, and (mostly),
lack
the burrs and ridges which will cut up the rather coarsely woven bushing felt.

There was something on this subject several months ago, but I cannot remember
which list it was on.  I do, however, remember that, as is so often the
case, Newton
had the best logic.

Spend the bucks.  Do it right...the first time.

Best.
