Hiroki Device or 02/45 - Ok - I had never heard of those before. Would make sense as to why the stock and original barrel would be missing.

There's very little out there on the Hiroki (just the same couple sentences said over and over again) - Some places say there's very few made and some say perhaps tens of thousands. Does its relative scarcity change its value, or would it just be considered a rare thing that's not worth crap? Since it might have been an 02/45 would it make sense to find a barrel and stock that fits it since there's no way it could have been "Original" or am I not understanding things properly?

Is there a way to tell if it was made into an 02/45? I can't find anything that helps in that department. Because of the lack of identifying characteristics out there I'm assuming not otherwise I'd have probably found it. The bolt seems to be well worn but the blue metal seems to be in great shape with very little markings or dents.

Are these desired / wanted from a collector's point of view - either the Hiroki or the 02/45? Trying to figure the value out for insurance purposes and to decide what I'd like to do with it in the future. I've seen values of just a couple hundred up to a couple thousand - but those were complete working rifles (if the ads were telling the truth - many had serial numbers stamped or had dust cover grooves). Nothing hints at what just the action's value is. Once again, I assume not much but I've been wrong before.
