If you're a long time reader here you may recall that back in the fall of 2021 I did a few posts on a building construction toy manufactured in the early 1960s by Toronto's Peter-Austin company. It's a toy that seems almost identical to the famous Girder and Panel toy manufactured by Kenner in that era.
What got me started on those posts was a paragraph in a book called Architecture on the Carpet: The Curious Tale of Construction Toys and the Genesis of Modern Buildings by Brenda and Robert Vale. The authors assert the Kenner toy "appears to be a commercial rip-off" of the one by Peter-Austin. Here's the complete paragraph so you can see for yourself*:
"It was not until 1956 that a toy appeared that imitated the construction of modern tall buildings, with a frame cladding. The manufacturer was the Peter-Austin Manufacturing Co. of Toronto, Canada. They made two different sets, the No. 500 Trans-Canada Highway Bridge set and the No. 510 Building Set. These sets comprised columns and girders made of rigid red polystyrene.11 The columns were pushed into a baseboard of Masonite (hardboard) with holes to receive them, and they were then connected with the horizontal girders to form a building frame of any desired height, which could then be clad with lightweight panels of thin, vacuum-formed plastic, the simplicity of the system allows for a variety of building forms. A year later, in 1957, Kenner Products of Cincinnati, Ohio produced a more or less exact copy of the Canadian sets under the names 'Girder and Panel' and 'Bridge and Turnpike' in what appears to be a commercial rip-off. Certainly pictures of both systems show remarkable similarities. As might be expected, the Wikipedia entry for Girder and Panel does not have the full story.12 It describes how it was invented by the president of Kenner, Albert Steiner, after he saw a new building being constructed in Cincinnati, but this appears to be contradicted by the pictures of the Canadian sets, which predate the Kenner product.13"
As a child I owned a Kenner Girder and Panel set and loved that toy. So, being born and raised in Toronto, I was quite surprised by the authors’ assertion that the toy was actually something invented and manufactured in my home town and possibly 'misappropriated' by Kenner. That seemed a surprising thing to say so I did a little digging to see if I could confirm or deny their assertion, the result being the posts. If you're interested in my 'investigation' from a few years back all the posts in the series, including this one, are tagged with 'Peter Austin Mfg Co'.
Investigations hit a dead end around late November 2021 with the mystery unresolved and no definitive answer in sight. However, after Vince stumbled across a Kenner set at a Toronto thrift shop earlier this summer the investigation was briefly rekindled.

| Here's the side of Set# 500: Was the original selling price $1.98CDN? |
Back in 2021 I was able to buy a beat-up Trans Canada Highway Bridge Set (Set# 502 as it turns out). It had only a few parts inside, no instructions or associated advertising material, and the box was in very rough condition. This summer another bridge set for sale on eBay was brought to my attention. It looked to be in very good condition so I went ahead and bought it. I was pleased to find it was in nearly pristine condition with a near perfect box, a complete set of parts, and instructions.

Above is the instruction sheet included with 500. It looks good.

However, things start to look a little odd once we have a look at 500's project booklet that shows a few of the bridges you can build. Its cover page tells the tale: it looks like the components used to build the bridges shown in the booklet are made from Kenner components! Inside is no different. All the projects appear to have been built from Kenner parts.

Ok, so let's look at the pages in the project booklet. It's just a folded sheet of paper, so this won't take long as 'booklet' is an exaggeration on my part.

At the top of each page you can see a set number called out. The implication being that there are 3 bridge sets, each with more parts allowing the construction of more complex structures. Or maybe they are just expansion sets that build on previous ones? I can't say for certain.

Yes, the site does state the Peter-Austin kits were released in 1956, but frankly, I can't find documentation to support that date. So far I'm thinking that the Peter-Austin sets appeared later, maybe 1961 or 1962, but I don't have a solid document trail for those dates either.
