This group would have been 1980-1985 not sure if it is a set although the dome
looks like a space base or robot head?
Thanks for the insight I thought it would be neat to build something using my
old Lego!
Most LEGO pieces have the LEGO logo on them. Although not all of them do, it
can vary by age and manufacturing period of the parts. Your parts appear to be
common bricks but don't have a LEGO logo on them.
You should sort out the pieces that you have and group them by element type where
possible. This will make identification easier on alternate brand sites when
and if you want to sell them.
It looks like a lot of them may not be LEGO although it is difficult to tell
because of the lack of detail in the photo.
I hope that you find buyers for these alternate brand products, if you choose
to sell them.
