Hi Guys (and girls)... I have some of the G1 minibots and need help trying to figure out which ones I have/need. I have 2 Huffers, but they are the same date stamp, both rub signs. I have a Bumblee, a Brawn, a Gears, and a Windcharger. I would like to know if these were the original 1984 or are they the 1985 that came with the mini-spies? I also need to know which mini-spy they each came with, so I can go get those as well. Thank you all!
