question on spange case

[steiner68]

hello,

how to differentiate a Spange case with a box for iron cross? (in the case when there is no eagle on the box).

thank you !

box

If you can lift out the base there are numbers

621KB = EKI
622KB = spange

And as Jim infers: These ''base codes'' identify which of the award/s would by ''convention'' fit comfortably into the actual recess size and shape.

Kind regards,

Marcus
