Likewise. The discs were still being listed in one electronics catalog in 
Canada in 1948, and I know of one movie studio using them for their playbacks 
that late, so old stock was probably discounted and people were still using 
them. The Les Smith collection (Toronto recording engineer) had some glass 
discs cut in the 50s, although these were mostly using up blank sides.
