DescriptionTubeless - No logo inside - other pips
From1956
To1957
The 13 generation is quite special, as it's identified by tubeless bricks with pip on studs. This type of pip is used on all modern bricks, but for older bricks, this mold is uniqe.
The available samples are primarily 2x4 bricks (of Dutch origin), but a few samples of 4x4 cornered bricks are also found (of Danish origin). The 2x4 bricks are numbered 1 to 10, while the 4x4 bricks are numbered 17. Red is the only color overlapping the two brick types, so it's possible that the 2x4 and 4x4 bricks originate from separate molds, but on the other hand, until more samples have been identified, the hypothesis is that these bricks originate from the same mold.
