Prop construction help

Probably not the right look for Airsoft but I wanted to make use of these dang nixies I had.

Take an old briefcase, 70’s ?

Throw in some older electronics

I am getting some old valves to put in there for good measure. :slight_smile:

While I can make it sing and dance.
Dressing it up is not my strong point.
Can anyone assist with making it look the part, whatever that is

I made these for us to use as C4 explosive charges.
