Like it or not, there was one facet of many a childhood that had the power to unify and divide - the swedger.

Access to popular snacks was often key to joining the social elite through the practice of play piece swaps on Scottish playgrounds, be they sweet, savoury, e-numbers or emulsifiers - many of which have been consigned to the history books.

One such product which is making its way back onto shop shelves is the Bon Accord drink, once famed for its smiley-face logo.

The Arbroath-based company delivered their last bottle around 20 years ago, but Karen Knowles hopes to revive the century-old brand established by her great-great-grandfather in a new line of sugar-free drinks.

Here are some firm favourites that weren't so lucky.

Shop owners were panic-buying Kola Kubes in bulk when Tangerine, owners of Taverners Sweet Shop, revealed it was bringing an end to their hexahedron sweet production.

The supplier also announced at the same time they would cease production of Sweet Peanuts, another favourite that left many retailers with a sour taste in their mouths.

Not quite extinct, the sugar mouse was a popular favourite around the UK, particularly at Christmas time, made using icing sugar, egg whites and golden syrup.

You may struggle to find them in your average sweet shop, however infamous Crieff confectioners Gordon and Durward continue to produce them - 3000 per week on average - in various flavours including raspberry, vanilla and lemon.

The concentrated meat product conceived in Edinburgh has an abundance of uses in the Scottish diet - be it diluted with water to drink, added to stews or even spread on a piece.

One evolution of the product saw the arrival of the Bovril crisp, an equally meaty snack whose disappearance sparked minor outrage and one Facebook page which amassed a total of 870 likes and one failed online petition.

Made from chalky sugar, bubblegum or chocolate, this controversial product was introduced in the early 20th century.

Many manufacturers produced them under various guises, from the red-tipped Popeye Cigarettes to the (perhaps more socially acceptable) Barratt's Candy Sticks - some came wrapped in papers, some even contained powdered sugar which resembled smoke when blown out the end.

They are still manufactured in some parts of the world, but countries including Brazil, Finland and Ireland have imposed bans on confectioneries that resemble tobacco products.

While we're on the subject of highly inappropriate childhood snacks, does anyone remember Top Deck?

Available until the 1980s, the drink was a low alcohol shandy available in a variety of flavours and marketed to children in the UK.

One of many Wispa products discontinued by Cadbury alongside Wispa ice cream and the Wispaccino.

The product disappeared in 2003, along with the Wispa Gold - fortunately the latter was brought back permanently in 2011.

The discontinuation of Toffos was a gruesomely tragic moment in British confectionery history - angry tirades were written, protest groups mobilised online and waves of grief were heard across the country.

However, one Broughty Ferry sweet shop miraculously brought the toffee-filled treat back in 2014, after a lucky shipment came through from India. Shop owner William Dunn had contacted Nestle in a bid to track down the staple of his childhood, but was told the company was in the process of fading Toffos out, even in the middle east.

His aunt, who resided in Dubai at the time, was able to track down a box of 95 Toffo mini-packs - which William put on sale to the delight of his customers.

Alongside the Freddo, Taz bars were one of the most popular tiny chocolate bars you could buy for 10p.

The Looney Tunes caramel-filled treat emerged alongside the relaunch of the Freddo in 1994, after the latter was withdrawn in 1979.
