Here's one that's been bugging me for years. Who supplied the electrical devices in Poverty Row efforts like "Voodoo Man" & "Charlie Chan in the Secret Service"? I've seen the same gadgets in several Poverty Row films & they don't look like any of the ones made by Kenneth Strickfaden. Also I think they are too early for Steve Karkus. Just though some of you guys might have run into this info while doing other research.
