[R-390] Squeaky Slugs

[Les Locklear]

This subject points out what has been a "pet peeve" of mine over the years...
 
R-390 "non A", R-390, R-390A.
 
There are only "two" ways to ascertain which version we are discussing.
 
Simple I "always" use R-390/URR or R-390A/URR when discussing matters that differentiate between the two versions/variants.
 
When I read "Non A" I delete the subject matter...
 
I'm 80 years old and crusty...
 
YMMV.
