Help identify Shoulder boards

[madtheswine99]

Anyone help in identifying these shoulder boards.

A Hauptmann (Captain) in some sort of Ulanen Regiment or Dragoons perhaps?

Believe the board is for Dragoner-Regt. König Albert von Sachsen (Ostpreußisches ) Nr.10
(Allenstein) XX Armee Korps

Actually, I believe the correct regiment is Oldenburgisches Dragoner-Regt. nr.19, garrison in Oldenburg, a unit of X.AK and raised in 1849.
A very nice & rare set.

It appears you are correct, hard for me to tell the color of the back ground of the boards. I guess it may well be faded black not dirty white. The Cypher is right for the 19th. Sorry for not reading farther down the my listing of boards.
