| I have just wondering if anyone knew when Lego started putting the part number
on the pieces. I have just found part 3176 which looks fairly 'new'
but has no part number. It just has the numbers 5 and 04 on the underside.
What do these numbers refer to?
Apologies if this has been asked before - I cannot find a thread.
Thanking you all

The one or two digit numbers indicate molds and mold cavities in the actual machine
that creates the parts from liquid plastic injection. As far as what year TLC
started putting part numbers on the parts themselves, I'm afraid I do not
know.

Part number such as 3001 for a 2x4 brick ? Certainly the older CA parts had that,
so it must have been in the earliest days.

The CA parts did have mold numbers (5 04) but not the part number (3176)

Thank you all for your replies. I am now going to pose another question - What
are 'CA' parts? Sorry to be so thick.

Cellulose Acetate plastic, which LEGO phased out in 1963.

Thank you very much. Everyday I learn something new from the forum.

You remember correctly but the roof 4509 coming with sets 7755 and 7727 in 1983
had part number since its earliest production.
Some old baseplates from 60s or 70s had also part number.
