It's an older model, from the late 90's, or VERY early 2000's. Eddy stopped using the Eddy sticker by the cage window around then.
If the padding goes to and is around the ear vents it will be a GT. If there is no padding around the ear vents it will be a Pro or Custom Kevlar.
Solid masks, as long as it is not one of the plastic "goaltec" model. I would pick it up if it were me, but then again, I am partial to them! Heck, the cage is worth that!
