NSKK collar tab questions

[JUNGCO]

I have an identity document to a NSKK man for the NSKK Staffel in the Niederland. What does the right collar tab mean?
The second is a Soldbuch for a Rottenfufer/Hauptkraftfahrer. He served with Kw.Trsp.Rgt.6 (speer) and then Kw.Trsp.Rgt. 5 (Speer). Should his right collar tab be "Sp"? His are blank and you can see the shoulderboards have a two color piping on them. What does this all mean?

It appears the man is wearing a "T6" on his right collar tab. Possibly, an early designation used with the Speer formations. The blank right tab in the 2nd photo would indicate he was unassigned when the photo was taken. He is wearing the standard N S K k shoulder straps in both images.

Bob,
These are two different men. Sorry if I wasn't clear on that. The first is in an identity book issued in 1944 and the second, the man was with Kw Trsp. Rgt. 6 (Speer) when the photo was put in the book (fpn L53378).
