The other film was filmed at Blaenau Ffestiniog and was the first "talky" in the Welsh language.
Yes, the winder is similar to that still extant.
Are you sure about the second film? It is silent on the web site (although it is not impossible for a silent to have had its soundtrack removed).
They show a sizeable gallery working. I would have thought that in the early 20th Century Bleneau would be pretty all underground or untopping.
Hmmm, interesting!
I have just watched
all of the film clips. There is something very odd there! That is
not the film I know as Y Chwarelwr! However, the clip with the family round the table eating
is part of that film! You are quite correct in saying that most of the film on that website is Dinorwic, I can even identify a couple of the places shown. If you go to the "Gathering the Jewels" website there is the Y Chwarelwr film on there. I will look for a link to it tomorrow.
The Y Chwarelwr film was featured a while back on S4C as the original final reel was missing and a new replacement was cleverly recreated with modern actors made up to match the original actors and also the modern film was made fuzzy and pale to match the original reels. They made a new soundtrack for the whole film.
