When LEGO tried to develop a larger brick for young children, they first experimented with Jumbo bricks. Soon, these were replaced by the Duplo size we stil know today. The LEGO designers tried several things, and as a result there are two very different versions of the 2x4 Jumbo brick x1446.   *  x1446 Jumbo Brick 2 x 4 Parts: Jumbo Bricks Samsonite verion Best known is the Samsonite version. These bricks were designed in Denmark using the metric system, but produced and released in North America. A 1x1x1 brick unit size would be 25x25x25 mm, minus (2 x 0,2 mm) tolerance taken from the ends to allow for building. The resulting 2x4 brick would be 50 x 100 x 25 mm minus a tolerance taken from the length and with to allow for easy building. As a result, the actual 2x4 brick is 49,6 x 99,6 x 25 mm in size. This is close to imperial (inch) based sizes, but it really is SI metric. The height including the stud (and logo) is 30,3 mm. The stud diameter is 21,6 mm, noticably larger than on the European bricks. The Samsonite Jumbo bricks are generally known to "not work with any other LEGO system", but in reality the size of these bricks IS exactly 5x the Modulex system. The bricks themselves don't connect with each other though. Samsonite Jumbo bricks were used in:   *  041-1 (Inv) Pre-School Beginners Set 24 Parts, 1964 Sets: Samsonite: Jumbo Bricks   *  042-1 (Inv) Jumbo Brick Pull Toy 9 Parts, 1966 Sets: Samsonite: Jumbo Bricks   *  044-2 (Inv) Jumbo Bricks 30 Parts, 1969 Sets: Samsonite: Jumbo Bricks   *  105-4 (Inv) Pre-School Beginners Set 24 Parts, 1964 Sets: Samsonite: Jumbo Bricks   *  300-2 (Inv) Jumbo Bricks 30 Parts, 1972 Sets: Samsonite: Jumbo Bricks   *  14-5 (Inv) Jumbo Building Bricks 60 Parts Sets: Educational & Dacta: Jumbo Bricks European version Less known is the European version of the Jumbo bricks. This seems to be mainly because they were made in smaller quantities and were available for a shorter time. The size of these bricks is exactly 3x the regular system. This seems to be a later design idea, leading to the 2x system size of the later Duplo bricks. A 1x1x1 brick unit size would be 24x24x28,8 mm, minus (2 x 0,2 mm) tolerance taken from the ends to allow for building. As a result, the actual 2x4 brick is 47,6 x 95,6 x 28,8 mm in size. The height including the stud (and logo) is 34,3 mm. The stud diameter is 17,9 mm, noticably smaller than on the Samsonite bricks. European Jumbo bricks were used in:   *  501-3 (Inv) JUMBO Pull Toy 9 Parts, 1966 Sets: Classic: Jumbo Bricks   *  502-2 (Inv) Pre-School Medium Set 8 Parts, 1968 Sets: Classic: Jumbo Bricks   *  503-2 (Inv) Pre-School Large Set 16 Parts, 1968 Sets: Classic: Jumbo Bricks Looking at the images (especially when you find better quality images of these sets), the difference in relative stud size is recognisable.

My jumbo bricks. Top right of block of 8 is a badly faded blue, not another colour. :) (3 months ago, Feb 7, 2024, to Catalog)

[...] I think that we should consider splitting these parts in the catalog. That would only add two parts, which can be easily identified. They would be the alternate versions [...] (3 months ago, Feb 10, 2024, to Catalog)
