Mark: You're right, those years aren't as well documented, but I think you can assume a discount (a WAG of 20%?) over the RKLT years, IF salt wood isn't an issue, and more (as suggested) if it is. I don't think you can expect most dealers to look at your gun and tell you that its retail value is $X,XXX (although you could probably pay someone for a written appraisal, if you're doing estate work or something), and I don't think you'll find any books that can do more for you than the Blue Book, which gives no more than the starting point you mention. Studying the market itself for awhile is your best bet, and the Internet is a great tool to do it ... for instance, I just hit the Cabelas website and they alone list seven Dianas. Now, are their prices, and those of other dealers and auction sites, realistic? That's for the market to decide. Superposeds are a facinating part of the fine gun world, because there are so many of them in so many variations, so many stages of wear, repair, alteration and restoration, and because there are so many buyers. Good luck. TT
