Looking For Info: Sessions / EN Welch Mantel Clock

I recently acquired this clock from my grandparents house. It has always been in there house since I was a little girl, my grandfather also remembers it when he was a little boy (he was born in 1920). But he never knew where it came from other than it belonged to his parents. My grandmother assumed it must have been purchased before 1920 hence her type written note attached to the back of the clock.

The clock did not work prior to my acquiring it and after some fiddling with the crutch wire? on the pendulum and making sure its on a level surface it has ticked, kept time, and chimed for the first time since my grandfather was a young man (maybe 1940-1950?). Yesterday I showed him a video i took of the clock working and chiming on the hour, it definitely brought a smile to his face! :)

I cannot seem to find a lot of information about this clock in particular. Specifically the year it was made? Model? I find similar from E N Welch, but in reading the history of the company and the fact that Sessions is also listed on the label, I'm assuming it's after 1900 when Sessions took over the company.

If anyone can help me in my search for more information, maybe a little about it? the model? the year? Or some resources or books where I could start looking for this info??

I'd love to share this with my grandfather (he is 94 years old today) and also write a short note about it to slip inside the case for my future generations and family members.

Thanks in advance!
