Ambika mystery parts

The Ambika i am building has these parts included. It was ordered on 13/10/2014

The order form in the box mentions : MB , SMR4 , SVF and 4P voicecards but there were a few extra pieces including some knobs , switch caps and other things.

The things below i assume are an LCD screen cover ? And some clear caps to do with the LED’s in Ambika panel control section. I’d really like to figure out how these in particular are to be installed.

Explanations

That is very helpful , my thanks once again !
