Here's the badge for my next ship, SMS
Hannover:
Thank you gentlemen
Regarding SMS Deutschland I'll admit that according the beautiful picture it seems that the badge had silver instead of gold as shield colour and instead of the emperial eagle in center there was the black and white squared ensign. But I will look into my sources to see if SMS Deutschland had changed the colours while he was in service. Maybe you have better sources to give a clear answer?
Regarding SMS
Deutschland: As you can imagine, it is pretty hard to find color pictures of teh badges, even though many were preserved over the years. The ornate, first version was replaced with a simple shield later in the ship's career, but the squared engsign remained. Your original version with the eagle engsogn might be used for the ironclads
Kaiser and
Deutschland, see the pictures below.
Here are two suggestions for the two of them ships: Both are just quick kitbashes, so feel free to modify/comment if you wish:
