FCI Consumer Guide Unknown Notation
 

In the back of the FCI Consumer Guide (an early FASA product) there are ratings for Availability and Reliability, with a set of rules on how to use them.

However, along with these ratings, there is also a number notation in parenthesis listed with each manufacturer. It's between 3-15, so I assume it's hexadecimal.

These numbers, along with the associated corporation, are compiled on a single page in the back of the supplement, as well.

Anyone have any idea what these are, or what they mean?

Page 36 implies that it the Manufacturer's TL, as opposed to the item's minimum TL.

Ah, I see it now. Thanks!
