Vintage LEGO Classic Space 6901 Mobile Lab

Description

Overall good used condition, but it is used and has signs of play and wear. See below notes and substitutions.
The 6 light gray supports have been substituted for black supports. One of the 1x2 bricks with space decal was missing and is replaced with a regular 1x2.
Some light gray pieces, like hinges, tiles, a 2x8 flat, and antenna, looks more light bluish gray than light gray.
Some of the transparent green pieces have cracks, but they still work correctly.
The space decals everywhere are a bit faded, as normally these pieces are in used sets.
No instructions or box is included.
