So, the white piece has identification, but the front cover does not. How are these identified? It's from an old space set from the 90's. I have tons of non typical parts that seem to have no identification. It does have some numbers on it - 1-02 what is that referencing? I know this was from a few sets, probably

The box is part 4345 (or a variant). On BrickLink, that gives This Door, Frame fits with the following Door:. And those parts are 4346. But you want one with a pattern on it, so the BrickLink search you need is 4346p*. There's only 60 of them, and one looks right: 4346pb05 Container, Box 2 x 2 x 2 Door with Slot with Red and Yellow Controls Pattern


As for "1-02 what is that referencing" it is almost definitely a way for Lego to track which part of which mold made that part, so that if any are reported as mis-formed, they can track it down more easily.

    Wow, I never knew you could search with a * match. That's going to be useful in the future! Jul 5, 2022 at 21:54

    The first time you see it, the potential is mind-blowing.

  • Thanks! I didn’t realize every part wasn’t identified! Jul 7, 2022 at 5:53
  • @SQLALLSTAR the round 1x1 brick <bricklink.com/v2/catalog/catalogitem.page?P=3062b> has been in use since 1976 in this form, but only in the past few years has it had any marking on it saying Lego, let alone a part number.

These parts are Tile 1 x 2 with Groove with Red and Yellow Controls and Two White Stripes on Left Pattern,


Note the similarity to this part (below). You can see the left side is different.


Container, Box 2 x 2 x 2 Door with Slot with Red and Yellow Controls Pattern, attached to Container, Box 2 x 2 x 2

4346pb05 4345

As for finding pieces yourself, I find the Bricklink search to be most useful. Obviously as you become more familiar it will be easier. Searching by colour is usually a good way to start.

To find your parts I searched "white tile 1 x 2 pattern red yellow" and "black container door"

    Unfortunately, some of the pattern descriptions are just things like "Container, Box 2 x 2 x 2 Door with Slot with M:Tron Pattern" which does not help. That's why I recommend searching with google instead of BrickLink directly - if you have a way to describe a piece, google will show you where other people have used that wording to describe it, while BrickLink can only show you its one standard description. Peeron used to have alternate keywords, which helped find things where you didn't already know exactly the right phrase.

    @RSchulz Good point. It's always possible to try both anyway. I probably find Bricklink easy because I have a pretty good understanding of their naming conventions (which is where gaining experience will help). Still, the number one best way is to search by part ID if you can find it (a 4-5 digit number). Jul 5, 2022 at 22:06
