I agree, Janice. I was fairly certain the blue one that was removed was Indiana. About the poster's clear plate -- The grapes on the right side (looking down at picture) cut off a bit short of the ridge that separates the rim from the center. The Findlay plates in the book have grapes going all the way to the ridge. This makes me think Indiana even without being able to pick out a lot of detail in the pictures.
I had one of the Model Flint plates in hand one time. The detail of the grapes and other details was much greater for the Model Flint than for the Tiara. If I remember correctly, there were also more bubbles in the Tiara plate than in the Model Flint -- I am fuzzy on this, however, so I mention it with caution. Without a good comparison, it was difficult to tell someone to look for good detail. The characteristics you mentioned are much more helpful.
