Magnetic focus and deflection, a slightly advanced CRT design, that could easily be converted to a newer 10BP4 type.
I realize that the RCA and others had magnetic deflection as well, but the old CRT's were harder to sub.  |
IIRC they also were experimenting with high definition too; something like 800-900 horizontal lines...Unless I'm confusing them for another maker (I know some maker in the US wanted more than 525 before the war).
