1947 is right around the transition from maroon to gold. The maroon box was used from 1946 to 1975, mostly on N frame revolvers, but also K frames came in this two piece box. The gold boxes also started in 1946 and ran until 1965. Bottom line is that the factory would print labels and stick them on whatever box the gun fit into, so you will see both colors used for the same models.

A 1917 38 M&P would most likely have been in a hinged light or dark maroon box. It will often have the standard end label with a ribbon label above it signifying a Round or Square butt.
