If you really want one for a collection, you DO NOT want a Mitchell. They look very nice and I bought one for my son who wanted one to shoot, not collect. He's really into the WWII gaming and has several WWII era rifles to play with. They are all Russian captures, have been remarked so the numbers all match (how convenient that they found an entire warehouse full of new, matching numbered rifles. Yeah!) and polished up the wazoo. But they're pretty.
These are definitely not collector's rifles. If you want one to play with and shoot, fine. But know that they are what they are.
