This is one of the real tuffies in the Hemingray No 18 style.EID[O7O] with a 162 crown slapped on rather than the standard 134 crown. I have gone to extra effort to make sure that this is indeed the EID [O7O] by taking accurate measurements of this dome, plus the domes from other 134 Hemingrays and 162 Hemingrays and comparing the differences. This dome's diameter is a lot larger than any 134 dome, at least by 1/4" and is the exact measurement of all the 162 domes I measured. Only 2 lightly flaked drip tips and a tiny fleebite to the WG lip's edge separates this from perfect. Upgrading will be rather tough to do from this one. Book is $100 range.
