The inconsistencies with the "L-Series" and their associated "KL" bezels has been annoying to me since before they were created.
L1 has no KL bezel
L2 has no KL bezel
L3 - no such model
L4 has the KL4
L5 has the KL5
L6 has the KL6
L7 has the KL7
L8 (KL8) and L9 (KL9) were never released.
KL1 was for the E1e and E2e, later as part of the E1L and E2L [I believe]
KL2 was for the M3 (low output version of the KL6)
KL3 was for the C2/6P (low output version of the KL5)
KL4 was for the E2e as part of the L4 (high output version of the KL1)
KL5 was for the C2/6P (part of the L5) (High output version of the KL3)
KL6 was for the M3 as part of the L6 (high output version of the KL2)
KL7 was for the 8AX as part of the L7
KL8 & KL9 were never released.
KL1 was a replacement bezel so it was understandable that it doesn't match.
Technically the KL4 was also a replacement bezel but it was also released 'straight away' as part of the L4.
(same applies to the KL5 and KL6 and KL7)
To my mind the L4 would have better been called the E2L (this was the obvious choice before the E2L was released as the E2e+KL1 I believe)
Another alternative would have been EL2...
The L5 would have been C2L or CL2
The L6 would have M3L or ML3
The L7 would have been 8AXL or 8LAX or perhaps just 8L...
Simple really?
