As long as we are talking about the various Bing offerings in their "basic" line we might as well remember the Vedes connection
This Bing set was sold under the VEDES label. VEDES is short for Vereinigung Deutscher
Spielwarenhändler. Which is a trade organization that specializes in sales to the leisure and hobby market – literally “play and leisure.” The organization was founded in 1904 in Leipzig and moved its main headquarters to Nürnberger in 1929. They took the name “VEDES” in 1920 and their first trademark was a Christmas tree with 3 candles and the name “VEDES” at the base – this is the trademark on the box lid of this train set (lower left of box cover).
Based on what I was able to find and translate from the German version of Wikipedia it would appear that VEDES is something like Montgomery Wards and, at least as far as the Bing trains are concerned, the marketing would be something akin to the American Flyer Nationwide Lines.
