Need help w/ Reflector/Shockwave KO question

I am watching two auctions from the same seller:
http://cgi.ebay.com/Shockwave-1985-Authentic-G1-Transformers-Rare-/290500060995?pt=LH_DefaultDomain_0&hash=item43a3272743
http://cgi.ebay.com/Transformers-G1-Reflector-Camera-Mail-away-1984-/290500064752?pt=LH_DefaultDomain_0&hash=item43a32735f0
I am suspicious that they are KOs, because the seller has no other TFs in his selling history, and I think the two figures were knocked off around the same time (quick google search).
However, one bidder asks if Shockwave has Made in Korea and Toyco on him, which the seller says it does. I went and checked my Shockwave (which I am reasonable sure is not a KO, and it says Made in Korea, Toyco 1983. Also, the Reflector is dusty and looks to have a little playwear.
So I have two questions:
1. Why did the bidder ask that question about Shockwave? What does it mean? (i.e. is MY Shockwave original?)
2. Is the Reflector original or a repro?
Thanks for your help everybody.
