That's not a full Boehm as full Boehms (Selmer's model 808 or with N.8 spec keywork) have 20 keys and 7 rings with the range to low Eb (see 1st attachment).
It's Selmer's model 804 (or N.4 spec keywork - see 2nd attachment) which is the model fitted with the LH forked Eb/Bb mechanism and articulated C#/G# mechanism which make the following easier:
C-Eb/G-Bb can be played as C/G (xxx|ooo), then lift off LH finger 2 (LH middle finger) to give the Eb/Bb (xox|ooo) which unlike long Bb (xoo|xoo), is in tune as both a lower register Eb and upper register Bb.
B-C#/F#-G# trill is done by holding the C#/G# key down and trilling with RH finger 2 (RH middle finger) just as is done on saxes - the RH ring keys will automatically close the C#/G# pad cup when they're held down. Also the extra 'sliver' key for RH2 is to give an easy C/Db, G-Ab and altissimo E-F trill as that duplicates the LH pinky C#/G# key.
You will lose the full fingerings for altissimo F and Bb because of the articulated C#G# mechanism as the RH ring keys will hold it closed, but you can still use the short altissimo F fingering and altissimo Bb can be played as upper register C with the left thumb off/uncovering the thumb tube while still holding the speaker key open.
Here's a list of Selmer's keywork spec/CT model numbers:
N.1/801 - 17 keys, 6 rings (your bog standard Boehm system clarinet)
N.2/802 - 17 keys, 7 rings (with LH forked Eb/Bb mechanism only)
N.3/803 - 18 keys, 6 rings (with articulated C#/G# mechanism only)
N.4/804 - 18 keys, 7 rings (with both forked Eb/Bb mech and artic. C#/G#)
N.5/805 - 19 keys, 6 rings (with low Eb and artic. C#/G#)
N.6/806 - 19 keys, 7 rings (LH Ab/Eb lever, forked Eb/Bb and artic. C#/G#)
N.8/808 - 20 keys, 7 rings (full Boehm - low Eb, LH Ab/Eb, forked Eb/Bb and artic. C#/G#)
Current Selmers with just the LH Ab/Eb lever (18 keys, 6 rings) are N.1B
