It’s me again needing help

Neiljones

The yellow ladder meets all the criteria e.g. size number of rungs but i can’t find Lego anywhere on it. Is this Lego? The other piece has 87748 on it but is not either of the two bricks listed on brickowl. Please help thanks neil

Search for Treasure Ring and you'll find it:

Could it be part of 892483? Might explain why there is no markings on it.

I think @Kaydee27 is correct. The missing third may have the identifying info you require but the fact that it comes from the late 70s could explain why it doesn't have a part number as (I believe) they were introduced in the 80s, and the lack of a logo is also not unusual.

There is also a 2 piece ladder listed, https://www.brickowl.com/catalog/lego-ladder-two-piece-complete-assembly
