–Black-dial Omega Constellation came in. Not perfect, but darn nice. And the accessories: box, original receipt from 1964 ($600 Hong Kong dollars), warranty in envelope, AND the COSC certificate!
–Portafilter + gasket came in from Cerini. Very strange: the new portafilter (theoretically identical to the one I mangled) works with both gaskets. It moves .5″ with the thick gasket from Orphan Espresso, and 4″ with the thin gasket from Cerini. The thin gasket seems to be the same as the gasket that came in the 54mm grouphead–from Cerini. It may be “correct,” but that’s the one that started leaking unless I really whanged it over. I’m going with the thicker OE gasket for now. That the portafilter goes in at all with this gasket suggests that the previous portafilter (also from Cerini) had different lugs, which I had file down to get things working. I think the OE gasket will be fine, especially as it wears in. Further: a 15g dose of espresso was hitting the dispersion screen seriously with the thin Cerini gasket. Hopefully this won’t happen with the OE gasket since the portafilter isn’t going in nearly as far.
