As a follow up to my 2020 post [id=609440788] I have since found one in amber:

(Top of lid - Counterclockwise) PATENETED MAY 25TH 1886 {Note spelling} (Underneath Lid - Center) 4 {Number is backwards so it is viewable through the center of the lid}

It appears to be from the same mold, so I would guess the back plates were used interchangeably, as my other one does not have a number 4 on the back.
