Your photo in message #1 matches the shield that I bought from BG.
Ebay vendors do not always have the correct photos on their items. However, if I see an Ebay vendor that is specifically showing your device, I would avoid buying from them.
Just select lowest price from Ebay. Your shield is still there although probably from different vendors to the one that sold yours.
I have never heard of any other shield with the Green Dog feature.
