I believe some Lamberts have a liner. I have three black Lamberts. One says Edison Bell Indestructible on the bottom, one is and IPLS French lesson, the third is in a red and black box that says The New Lambert and it has a liner. It is 5077 Fol the Rol Lol by H Bluff and has what appears to be a hard plastic liner. All have raised letters. I have an Indestructible with the metal bands, 653 that also has raised letters. Even after all these years I have not memorized all the different cylinder companies. Steve > > I'm still reading online articles. Lambert was put out of business after numerous infringement lawsuits by Edison. It's said that when Lambert finally folded (records produced 1901-1905), TAE got the patents to Lamberts' celluloid records. > > However, he didn't introduce the celluloid until 1912. This suggests to me that these "other" companies who made celluloid cylinders kind of snuck in (1908-1912 generally) while all these lawsuits were going on, and before TAE put out his first EBA. Does this sound about right? > > And how did Indestructible manage to keep making records until 1922, without TAE eating them up too? :) > > PS: I read that Lamberts were pure celluloid, no liner or metal frame. So that question is answered.>
