Question about a Half-Track

Hi folks,
I’m studying my instructions to a Das Werk Sdkfz 250/1 Ausf B. I came across this in my instructions and I can’t figure out this part of the model? Thanks in advance for your help.


Which part?

MA6, MA1

Thanks in advance

Its really for the -5 version, which is not correct for a -1. Dragon has left parts in for their -5 version in their -1.
Its a case for a binocular sight.
