I'm not sure the top right is a peltier. The top left two I would consider to be alike as far as type. The bottom right two I would call alike but not the same as the other two, and the bottom left, one looks like a sunset and the other I haven't seen before that I recall.
Hmmm. Pics must be arranged different on your screen? On my I have three pics on top row. Middle one is the red/white/blue. Pair on rite: Yellow/white and then red/white. Last pic on bottom are both red ribboned. I'm guessing it is the red/white/blue one you think may not be pelt?
