|Charles Cowie (1)|
I got to know Charles Cowie when he sent some information about osmium phonograph needles and pen nibs. He's been collecting elements for a while too, and it turns out we made many of the same choices for samples. I traded one of my "osmium" photograph needles for a selenium rectifier of his. His email is email@example.com.
