My psychic powers tell me there is a patent date of June 29, 1897. This is a New Royal patent.

PS---Must have been a Department or Hardware in LaReine, LA that had their own line of sewing machines over a long period of time. The different models and makers of machines came and went but the "LaReine" badge remained the same. Davis also seems to have been a supplier to this outfit and possibly many others.
