Prague Silver Box & Unknown Maker J-H

[Buttrflygrl617]

Hello Everyone
I would like to say this site is a blessing for anyone with a passion for heirloom silver. I have been able to identify so many maker's and pieces over the last couple of years by reading "Expert" replies to some very intriguing questions. I only can hope that maybe there's someone who may know the maker of my newest treasure. I know there's very little known of the Prague artisans that made the beautiful silver pieces like the one I have but makes hopes are that someone here might know. The history is what brings the box to life. I do know the hallmark is 1867-1922 and 3 is 800 fineness with C being Prague.There are 2 punches with maker that look somewhat different. One clearly looks JH and another may be JK. I do feel fairly strong that it is J(center dot)H. Would anyone know who the maker might be and any history on this artist?
Thank you
I am unable to get my photos to post here so I have included a link to my Onedrive folder where they are located!
