Here is a page to see the rarity of your nagant to give you a judge for yourself:
Rarity of Mosin Nagant Rifle Variations
Also I looked in my "Standard Catalog of Military Firearms collector's price and reference guide" it lists that gun as Exc.-$300, V.G.-225, Good-200 and so on. I think by your explanation that it would be in the V.G. to Exc. range. But... real world prices I've been seeing 1952's go for more!
Hope this helps.
