Radio Research
Global communications provide radio collectors an effective means to
share knowledge and coordinate efforts to answer radio-related mysteries. The
answers to some questions may already be known to a few collectors and only
require wider publication to the community, while other issues may require
a compilation of data from various sources to solve a question.
RCA Radiola IV Serial Number Registry
Production figures for some early RCA Radiola models are known
and published. See "Radio Manufacturers of the 1920's"
by Alan Douglas
as an example. Some of the RCA models were made in surprisingly few
numbers to begin with, so knowing how many were made would be helpful today to
give the aspiring collector some relative insight to the current availability. The
elegant Radiola IV
was manufactured by General Electric and marketed by RCA in 1923 as a luxury
model, and today seems relatively scarce. Unless someone already knows
and can document how many Radiola IV's were made, we will collect serial
numbers from visitors to this website and publish them here to establish
a range of numbers as a possible indicator of production.
