Super job on the photos, really excellent. The V you're referring to is, in my opinion, not a deliberate mark but cold-work cleaning up of the pontil scar. As for the Ikora attribution, I'm not certain, and would have to handle it to be sure. But, the handles are definitely similar to those used by them occasionally, albeit usually on Myra pieces. Without handling the piece, I personally can't be sure, but my instincts tell me uncommon Ikora at this point. FYI: the only pieces of Ikora I've seen which have been uneven or leaning are experimental pieces, or those made by apprentices, which could explain the handles too. However, one must be extremely careful in such circumstances - remember the handled "Monart" piece in the Ysart Glass book.
