The video clip by Peter Burges is from the film 'Y Chwarelwr'.
Made in the 1930's in Blaenau Ffestiniog town and the quarries. It shows quite a few scenes from the quarries and the town.
It was made in three reels and the last of the three reels has been missing for several years, but the original script had been saved.
About four years ago the missing part of the film was re made using similar locations and using actors which resembled the original.
The finished film was shown on S4C tv and many people recorded it off the tv. The film and a documentary about the film was then made available for sale.
It was a drama about a slate quarryman and the family life.
Bellach dim ond swn y gwynt yn chwibian, lle bu gynt yr engan ar cynion yn tincian.
