I want to buy a blank German ID disk, and stamp it with some information, but in order to do so, I have to provide what I want stamped on the tag. I have an 18 character limit on it.

The soldier I'm going for, belonged to 5th Kompanie Grenadiers, 613 Regiment, 203rd Division. His roll number is 9214 and blood type A. So if I'm correct, is this what it would look like?

9214 A

Ers. Btl. 328 ?
