What would be the correct case that a German, triple marked, ADXXXX Sig P229 357 Sig would have shipped in?

Thanks in advance

My guess would be the gray plastic case with the Sigarms logo in a circle... the smaller one.

Tom, your serial number should have 5 digits after the 2-letter prefix. And the gun should originally come in the SIGARMS logo gray plastic case inside the soft outer cardboard sleeve.

12131 you are correct.
Thanks all, much appreciate your help.
