Hallo Kurt Peter,
ich habe Deine Anfrage weitergeleitet und folgendes hat sich ergeben.
I tried to research the arms. But it�s not very easy, because the tinctures
are unknown.
But in the way you descripted the arms must be the old arms of the
Archbishop of Cologne:
Blazon: Quarterly of argent, gules and azur. 1 A cross, sable (Cologne), 2 A
horse argent, rampant (Dukedom Westfalia), 3 Three leaves of water-lilly,
or, (Dukedom Engern) 4 An eagle displayed, or.
The escouchon in the middle is the personal arms of the reigning Archbishop
in this case it could be the arms of the House Wurttemberg or of the Graves
of Landau!
Ich hoffe geholfen zuhaben.
