I found these two photos on-line: the four-engine is a Boomeroo brand Avro York and the single-engine is unknown but possibly the same brand. The owner states that the Boomeroo is very rare and has a wingspan of over 14". I clearly remember seeing, some years ago, a photo of an Australian Boomeroo brand toy Lancaster, but the photo was so small I could not tell how accurate the model was.
Author also states his Boomeroo Avro York is tin plate, but it looks like a Wyandotte steel toy in its construction. It also has a decal that reads "British Airways York."
I know Dinky Toys also made a York as a die cast toy, that this plane was used for a short time in the late 1940s as a passenger transport but was still flying in some Asian countries in the 50s.
