GF SR Pill Box brake van - what are the loose bits ?

[Braddito]

Hi, the coupling hooks are clear, but what are the pantograph like detail pieces and where should they be fixed please ?

Thanks in anticipation of guidance.

Brake gear detailing bits. For fitting under the chassis. Not sure how one is able to see the detail with all the footboards, etc., I haven't fitted them (yet).
