Transport Visor or...

[Normandy]

I'd like some opinions on this visor. I'm thinking it transport rather
than Medical, the piping is blue but not a dark blue.
Other than the moth nips and what seems to be an attempt at
repairing them, its a nice looking visor with a high peak.

Its color is a light gray green and the material is soft...doeskin?
The insignia are on tight, no movement. On the inside of the visor the lining is a gold color and the diamond is marked Sonderklasse.

Can be TSD? J

[Normandy]

The word / term Sonderklasse, was that used by different manufacturers? Or was it attributed to Schellenberg?

As for TSD Truppensonderdienst, this organization was formed
towards the end of the war...'44? So if one could figure out the maker
and possibly when the visor was made, we could say yes or no to the TSD.

I see medical.

I'm with Joe - looks like Medical to me as well. Even with pics like these I think the Royal Blue of TSD would show more of a contrast with the field-grey wool top and bottle green cap band.
