Beautiful Snubbie. How about a guess that it was a re-seller's or collector's tag and not an original shop-keeper, since all the information you need to know was on the box? I say this because the price of that revolver may have been around $65 in the 1950s. The 1950s Masterpiece line was $70 in the 50s . . . or maybe the original shop owner inflated the price to increase profits? What are those stocks made of? I would guess ivory, but have never seen ivory that white?
I should have prefaced my guesses by stating that I was making the assumption that the gun was a no-dash from the 1950s??
