I purchased all contura covers from https://www.waytekwire.com/
44437 Carling Technologies VVCBC00-000 Plastic, Black, Amber Lens Contura III Actuator 0.74 ea
44435 Carling Technologies VVCZC00-000 Plastic, Black, No Lens Contura III Actuator 0.74ea
44381 Carling Technologies VRT Actuator Removal Tool for Contura Rocker Switches 3.02ea
These are the hard plastic versions, not the 'soft' ones that turn to rubbery goop.
Blue sea and other have the covers at 10x the price...
