Trim tag bona fides

Is this a real trim tag?  The 3KL is suspect to me since I thought K was already part of the L (RS) option.  Input appreciated. Thanks

Hmmm, I thought 12B might've been a bit early.

is it my comp?? or my eyes?? or the foto?? What exactly does it say there?? the 3k is not a big block designation...i can't make out the 4th option group code??? I'm gettin' old..anyone??

a better pic would help..... thanks!!

Ya, bad photo. 

The 4th option group says N, for the L35. 
The 3K is the trim group option, which I thought was already included with the RS option. I haven't seen a 3KL sequence before.  I've seen 3L and 3SL and 3BDSL, but not 3KL.
