Hi,
Thanks for posting and welcome.
It would be interesting to hear more about how you were involved in the designing of the mold...
Somewhere I have an original Calvert ad showing the entire set of flasks.
These bottles do turn up regularly on ebay. There is one of this mold there now.
This link will get you to the post-1900 bottles category and focus on on this bottle.

It's probably a bit more work to find one with the Calvert label on the neck like shown in the photo.
