So this beauty was a gift from my wife's grandmother, who knows how long she's had this thing, but was trying to get a date and not sure how to read the 2 numbers on the bottom?? Also what is the name for this type of closure? It's hard to get a good pic of the base, but the one starting with 5 looks like it's followed by a 7 at some angles then an 8 in others?? Is it possible the put an 8 over a 7
