To SS knots on pictures:
-first LAH band , hard to visible details of knots, period 1934-36
-4 SS soldier of 1.Kraftfahrer company, Rgt Deutschland, i assume period middle of 30ies maybe later, the knot looks like with circle runes on stem
-soldier of Der Fuehrer has post 1936 cap, different knot without circle on stem
-soldier of Oberbayern has probably same period or earlier, the knot is with circle runes stem
-soldier of Oberbayern with M16 helmet, combat SG84/98 bayonet and same knot
-3 SS NCOs of Rgt Deutschland, early period pre 1936, small caps, similar knot with different colours but with runes in circle on stem
For me is important to know which period is it, the uniform of various parts of SS changed about 3 or 4x in time, so is important the dating. Evidently is the using of knots of small dimension, not sword knot marked on stem with circle runes markings.
The piece on dress bayonet is of war period as white is replaced by grey color. best regards,Andy
