These radios were made by Strombecker. All radios on the back row are 1" scale; from the left, the dates of production were 1936, 1938, and 1931. The art deco blue radio, part of their "Modern Design" line, was first marketed in 1938. The table radio was listed in their catalog in 1934.
first on the back row left is the US Menasha Woodenware radio from 1934;
US Converse produced this radio as part of their "Realy Truly" dollhouse furniture starting in 1931; the radio last radio on this row was made by UK Barton around 1957.
On the front row is a radio made by US Nancy Forbes circa 1940; US Kage made the second radio from 1938 to 1948; the last radio was made by US Strombecker in 1942.
Plastic dollhouse furniture became popular after World War II. The 3 radios grouped on the left were made by Renwal. The open drawer housed the phonograph...this is almost an exact replica of the Philco radio that my family had in our living room. I remember when I was old enough to play my colorful cardboard records on the phonograph without supervision. I sometimes see old cardboard records on eBay. :)
The next two radios are almost duplicates...the dark radio was made by US Ideal and the brown one by Canadian Reliable. The only difference is each radio has their brand name posted on the front above the dial. In Zillner's Furnished Dollhouses 1880-1980 she says that "Reliable was licensed by the Ideal Toy Co. to copy some of Ideal's products." That explains the identical radios. The last radio was made by Jaydon during World War II.
Not only did Renwal have a phonograph in the opening drawer, they also had radio tubes and speakers as seen from the back!
