First off, I'm one of those pathetic throwbacks to gen 1 that just can't see past it! (except for MP's, some alternator/binaltechs, universe 2.0, you know, anything gen1ish). I have always loved the pre-movie gen1 stuff the most (84 and 85). After learning of the diaclone and microman history I loved them even more and have done a ton of reading on the pre-transformer japanese days. Back in the day I had about 20 or so gen1 from prime, starscream, some mini's to abominus and computron, pretty spread out from 84 - 87. Then about 10 years ago I bought most of 84 and 85 that I didn't have from digital toys/bantha trader. This was before ebay and before the prices had gone up much. I got lots of boxed but one of my proudest finds were 2 diaclone drivers, 1 in my wheeljack and 1 in my hound. I found out later these weren't even with the right transformers/diaclone bots and I have no idea how they got there but I was glad. Today I just receieved this for $61 shipped off ebay. It is as mint as my MIB purple prime and the roller launcher works perfectly. All I'm missing to complete is a right fist and 2 extra missiles. The stamp on the trailer appears to be the very first run of transformer prime, according to It's Prime Time! One day I hope to get a few true diaclone boxed items but this is a great start and I felt like a kid when I took the pics. The metal plates are super shiny, I couldn't believe the plastic on the trailer tower and roller and all of the inside, super minty. This just rules!
