There might be a faint 6 just to the right and above the Castello stamp. If memory serves, I wasn't sure when looking at the actual pipe whether it was real or I was imagining it.
BTW, @daveinlax, when you wrote in an earlier post that "none [of your Epocas with stick stems] have a straw size stamp" were you referring to the "hand made Castello" stamp that recent stems have?
