an uncle of my wife's gave me this DE and i don't know what it is... he said is a gillette but... please 'enlighten' me

i cant seem to figure out how to upload pics without hosting them up on another site first but ill give an exact description,please bare with me.

so it's a TTO with blue plastic handle and another metal knob at the bottom,
non adjustable and a little on the agressive site compared to my plastic wilkinson DE,and it opens at the top under the head.

thanks alot and if u have a pic of your own please post it .

thanks alot,cheers
