Picked these two things up with a few other insulators and want to no more about the strain. It measures 3 1/2" X 2 7/8" dark blackish/brown and only embossing is CGE. The other white piece I have no idea what it is but measures 4" X 1 3/4". On the bottom in two recessed diamonds is S S also embossed is P628. Any help as to what the CGE stands for and any value, and what the white piece is? Thanks in advance for any help. Got the info I needed, thanks James!
