You need to be happy with them! A couple of notes for future reference though.
1) Inspect the knife when you get it in; because once you sharpen / modify it you complicate any return process. But most dealers will pay for you to send the knife back to the factory and work with them to insure your concerns are taken care of.
2) Your pin problems seem opposite ends of the spectrum. One you don't like because they spun it down in the bone; the other you don't like because they didn't spin it down into the bone. If they spin into the bone there will be a circle (and possible chipping) that many times cannot be buffed out. If they do not spin into the bone, it's cap will be extended a little above the bone. Spinning all the way down is very difficult on smooth bone. Spinning into jigged bone without chipping is hard as well. Thus before you send them back you might want to tell them if you want them spun into the bone or not. On the red bone it looks like the backspring pin had to go right into a bone ridge, just bad luck during assembly. On the primitive bone, it should have been spun a little more snug; but they may have been gun-shy on hitting that smooth bone.
Most sellers will inspect knives as they are packing them for shipment, but knives are made by humans and most times not completely perfect. Great Eastern knives are unique in that you can see the human in every one of them; if these issues you are seeing bother you, then 100% out of the box satisfaction is probably not going to be achievable. But, your dealer wants you to be happy and Great Eastern Cutlery wants you to be happy; so just keep pounding into the factories head what is and is not satisfactory to you. You will be doing us dealers a service as well as the end customer. Most every dealer looks at the knives before shipping; and if you look there will be a thread about one slipping by most all of them. What matters is how it is resolved. The only way to insure you are getting the knife perfect for you is to go to a gunshow and pay 50% too much for it.
If those knives were still as you received them, you could send them back to the dealer and the next 15 customers he sent them to would be tickled with them. But this hobby is about making sure every person gets what they want....
Long story short: If you are not happy, decide what work they need done to them and send them to the factory with a detailed note. This will help them understand their customer base expectations. Most times if a dealer sends them back, they just figure they have an anal dealer as opposed to real world customers. Send your dealer a note and they will probably agree to pay shipping for you.
I'm telling you all this as if you had called me directly as I recognize your name
