I'm trying collect all the original classic space Minifigs in as early moldings as possible. I've read a previous thread on here about torsos etc, so I know what I'm looking for. I have all 5 colours in new condition (from sealed boxes). The white, red and yellow figures all have hollow torsos (no prongs) and thin chin straps. The blue and black models have small prongs and slightly thicker chin straps which is what you'd expect given the year they were released.
However, I often see the blue and black models advertised on bricklink with thin chin straps. I'm unsure if these helmets have been retrofitted. Has anyone here actually opened a sealed box of a blue or black figure that has a thin strap? Or a completely hollow torso?
I have the feeling the thin chin strap helmet may be original, but I'm doubtful there are hollow torso blue and black minifigs.
Oh and one last thing. I've seen that stickered blue and black torsoed figures have catalog entries on bricklink, but I'm doubtful of their authenticity too as the pictures shows a square sticker on the black minifig and the figures are not associated with any sets...https://www.bricklink.com/v2/catalog/catalogitem.page?id=64902
Thanks for any light you can help shed on this.
