I am not sure as when I went there I didn't look at the accessories (too busy drooling over my first look at g1s irl) but I am pretty sure I saw some purple thingomobobs that are his accesories. I'm gonna go check sometime but then again I can get them cheap off ebay and the like. No box btw. And is it me, but is g1 optimus prime a lot smaller than it looks in photos? A lot of those guys were waaaaaayyy smaller than I thought. Blitzwing's a midget lol.
At 16cm Optimus Prime was the largest Autobot toy released in the first series of Transformers in 1984. He was also the second largest Transformer at the time, the tallest being Soundwave (18cm). Take a look at the Classicsverse & G1 Comparison thread for a bunch of photos comparing contemporary Classicsverse toys with their G1 counterparts. In some cases the G1 toy is smaller, but in other cases they were bigger. It all depends -- but have a look through that thread and you'll see lots of side-by-side comparison photos.
Aside from getting an online checklist of its accessories, the other thing is to watch a few good Youtube reviews to get an understanding of how it transforms, and possible areas of breakage (if any) to look out for.

Good luck with Trypticon. I was just at CRU this afternoon (scouring for MTMTE #8 without luck), and saw that your future-Trypticon was still sitting quietly in the corner.
