is this 10-back legit?

[mikey see]

Hey there, sorry for the potentially amateur question, but... is this Mikey a legit '88 10-back? I've been collecting TMNT since I was a kid in the 90s but never went after MOC. I came across a seemingly good deal for this guy though (as well as Leo and Donatello) and figured I might give it a go. What's giving me pause though is the nunchucks - I thought the original runs were all the super slim wire of plastic that broke if you sneezed? This looks to be the thicker style I'm used to seeing in the later runs. His belt is also strange, the "clasp" seems to be way off to the side, like the recess for the buckle isn't aligned correctly with the peg that goes through the buckle. That's hard to explain (and photograph) but hopefully that makes sense.

Anyway yeah, I'm realizing I don't really know what I'm looking at. There aren't any obvious tells like a Nickelodeon logo and the date and legal etc look right on the card. There's also an old Target price tag on each of them for $4.49 which seems right. But what do you turtle scholars think?
