Back row from left, a 1970s TV from Hall's Lifetime Toys; white TV from Strombecker circa 1960; large cabinet TV made in Germany and imported by the toy store FAO Schwarz in 1966; this next TV came with Dol Toi furniture, but one very similar is shown in Marion Osborne's book, Barton's "Model Homes", circa 1959; last, unsure of maker but could be Barton or Dol Toi.
Front row on left also shown in Marion's book as being made by Barton 1970s; unknown maker on this TV, made of plastic with wood veneer strip casing. UPDATE: Thanks to Sue Freebern who helped identify this last little TV as a Lundby product from 1960!
Marion has written 3 very informative dolls house books; in addition to the Barton book, she has Lines & Triang Dolls Houses and 1914-1941 A-Z of Dolls Houses. Information on purchasing these books can be found on the http://dollshousespastandpresent.webs.com magazine website.
Now to get all these little radios and TVs back into the right little houses.....
