I've learned a little more about the plates in the last hour. The Model Flint operations were moved to Albany, Indiana in 1893, two years after the production of the plates began. Production of the plates was later done by Indiana Glass, which continued production of them for 50 years. Indiana licensed the design for use by Tiara and probably made them for Tiara to sell.
The first plates made by Model Flint of Findlay are supposed to all have a pale halo emanating from the head of Jesus. It is not a ring like we see in pictures, but more a roughness of the glass to show the energy. I haven't been able to find a colored version of the plate yet, only clear or clear with flash.
