Sure, and yes it does.  Leitz made orange clip-on windows for the LTM
cameras as follows:

ORAKO (also, 65,920/14057)		black mount for Leica II, III, IIIa	1936 - 1962
ORAKO-CHROM (also, 65,922)	as above, but in chrome mount		1936 - 1939
OKARO (also, 65,925/14058)		chrome mount for IIIb, IIIc, IIIf, IIIg	1939 -
1962

The ORAKO cost $1.50 in 1939 and $2.70 in 1962;  the OKARO cost $1.50 in
1939 and $3.00 in 1962.
