Hello, I recently purchased a Thundercracker on eBay with no markings. I did some research and it may or may not be an Diaclone. Apparently Diaclone's still have a datestamp but this one has NONE at all. I read that there are 3 markings (or the lack there of) for Seeker Jets, 1) None 2) Takara 3)Takara/Hasbro . So this leaves me to wonder, is my Thundercracker still worth as much as one with a Takara stamp? Or would everyone think its a Diaclone. Even Re-issues have stamps.
