| 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.
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:
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:
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.

This one is still a mystery...
Was this the original color, or was it chemically treated...

| Like the colour but seems very odd, doesn’t fit colour scheme for period.
Another faded blue treated perhaps, hope you find the answer.

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 for:
The inventory updates would be very easy to make, there was no mixed use because
the bricks are not compatible.
The x1447c01 might have used a different color 3001oldb on the end of the string,
but I have not been able to confirm that yet. I would explain 3001oldb-bricks
that have been found.
The x1447c01 still need an inventory consisting of the cart, string and 3001oldb.
Sadly, I don't have one yet.
