Hello everyone. I've been trying to do some research, but I can't really find an answer. How can I tell between a g1 prototype pony and a pony that someone was making into a custom, but for some reason was unable to finish? I know prototypes are rare, but they do pop up occasionally. There is someone somewhat local to me who is selling some that she swears they are prototypes. I can tell when it's a poorly executed custom, but I know there are some amazing artists who can make it look like the real deal. Thanks for any info.

A while back I read on Facebook that some of the g1 sets were marked either Hong Kong or China. I started checking the set that I knew about and I discovered that I did have both of the "Blueberry Baskets". I checked my other dublicates, but none of them were marked differently. So, I'm just wondering what other sets had the different markings. Any help would be appreciated. I hate to think that I passed one up because I thought it was the same pony that I already had. Thanks in advance.
