Mold Blown Glass Pitcher Pat. 1865

I found identical one with a lot of info but wonder if someone can add something more to the subject?

At the time the pitcher was made the industry called that pattern "Cincinnati." If you can find the patent, I'll bet it deals with the handle, pressed when the piece was made.

 

Yep, that’s what the patent is about, forming glass with the handle.
I though it’s an interesting piece, not the rarest one out there but still not that many for sale. To my disappointment, no interest at all after listing, starting at $49.99.
I seriously don’t understand what sells on the EAPG market.

 

Kard, do you have the patent, whose name is on it?

That puts it as a product of Gillinder Glass, Philadelphia. It's probably flint. Unfortunately, as the collectors of flint glass sell their accumulations, the value has been dropping for probably 15 years. The note on it probably indicates that it was made immediately after the patent was issued, before they had an opportunity to mark the mold.
