Title

[D8132ZBN], Letter from Charles Batchelor to Thomas Alva Edison, November 19th, 1881

Editor's Notes

"I find a big fault in the Opera machines." Commutators on all of them made such that after running for a while, the coppers raise up or micas lower down requiring filing of coppers. "They don’t seem to be made anything like so solid as the old machines in the commutator."
