I only have one boxed Pre-War revolver in factory nickel, and that is a 1917 Pocket Positive. Its label is what appears to be yellowed white instead of the blue found on blue guns. Its label states "Nickel" right on the label (not an added sticker), but the label does not mention the stocks at all, which happen to be pearl. There is no sticker so indicating.
From what I have seen, special features, like pearl stocks, or an engraved gun, will have a small, paste-on sticker stating the feature, usually stuck on the lid above the end label.
Any box without a serial number has probably had the serial number erased, as most Pre-War numbers are written pencil. Again, I suspect there are exceptions due to error.
