Hi everyone! A thing that has kept me puzzled for years is the weird size system of the 50´s smocks and trousers. Or actually systems, as there appears to be two different ways to mark the size that the Belgians used.

Example A, the simple 1, 2, 3 and so forth:

T.1 42/50

T.2 44/52

T.3 46/54

T.4 48/56

T.5 50/58

T.6 52/60

Now these numbers could indicate chest circumference divided by two (the common European system), as in 84-100 cm, 88-104 cm, 92-108 cm etc.. None of these numbers seem to tell anything about the length of the jacket and sleeves seem to just grow a little bit as the sizes get larger.

The really odd system is the markings that most Jigsaw smocks and trousers use:

602-0242

602-0243

602-0244

602-0245

602-0246

It seems to me that the first six numbers never change, only the last one. Could it be that the last digit is actually the T. number as in the earlier example?

If there´s anyone out there with any info on these I´d really appreciate to to learn something about this stuff.
