In which set is this LEGO brick used? There is no number in it and it's original LEGO. The only number on it is "A 1".

The specific part (870) is identified in the other answer, however it is part of an assembly with its own part number:


827 Vehicle, Tractor Chassis

870's page mentions it has extra parts that it is used with, and 827 is the complete assembly (steering wheel + mechanism).

This page details what other parts are needed to complete it.


870 is the base in the picture, and 871-874 are the mechanism pieces.

    I've seen people post add-on answers elsewhere so I figured it would be fine here - especially since when I started searching there was no answer yet Commented May 25, 2020 at 14:29

    Okay, but in that case just edit your answer to explain that you're posting this to add some context and don't say "this is the real part" because we already know what the real part is. Commented May 25, 2020 at 14:30

    Oh, with that I meant that while this is the specific part, it is useful to know that it is not a standalone piece. Not good with words, will try to reword it. Commented May 25, 2020 at 14:32

    I disagree with mindstormsboi here, your answer is just as valid as the other one. Also your answer in original form was fine. Commented May 25, 2020 at 22:59

That's Vehicle, Tractor Chassis Base 11 x 2 x 3

Following the link to bricklink, you can see that it was in four sets in the 1970's.
