I bought these two Imperial visor caps at the recent SOS. Apologies for my less than stellar photos; I will post better ones later, if possible.
One is a Dragoon officer's version, that would be worn by either of the two Garde Regiments, or the 1st, 5th, or 13th line regiments. It has just a trace of a gold cypher under the crown. Made of high quality doeskin.
The other cap is an nco's for the 3rd v.Zieten Hussar Regt.
There were a number of nice Imperial visor caps to pick from at the SOS; most were prewar full dress versions, rather than feldgrau.
