AtoZ (Metal Mechanic) Construction Sets

AtoZ (Metal Mechanic) construction sets have parts similar to both Eitech Construction and Meccano and are classified as Polylong(1a) type sets. AtoZ is the brand name of Padgett Bros who are a Major Importer & Wholesale Distributor of Toys, Nursery Goods, Pre School Toys, Branded Items, Arts & Crafts, Tools, Housewares, Garden, Pet Products & Grotto Toys. They have a website https://www.padgettatoz.co.uk/BOYS/METAL-MECHANICS-463 from which the pictures of additional sets shown below were taken in summer 2020. Whilst the boxes all have the AtoZ logo on them, the instruction leaflets are obviously generic as the do not have any brand name on them. They are almost certainly manufactured in China. Judging by the various styles of sets they may well come from more than one manufacturer. Some of their sets just have there logo and name details stuck on over other information (probably for a different company). Interestingly the AtoZ model of a Spitfire, the IWM model of a Hawker Hurricane and the Haynes model of a Spitfire all appear to be the same model.


Manufacturer / Distributor

AtoZ is a brand name of Padgett Bros, UK, who imported the sets from China.
