Recently I have bought 5 kilograms of Lego. The lot contained several sets and quite a few red/blue/white and yellow bricks.
The yellow and blue bricks are strangely coloured, some bricks are bright yellow, which looks pretty normal others are a pale yellow. It looks like they are discoloured, but throwing them on a heap they sound different than new lego. The lego logo is on the studs but very difficult to read.
Could this be a false kind of lego or is it old(samsonite) lego??
Another thing is that the 1 x 4 bricks have several different pins on the bottom side, I have never noticed all this variations. Is this also some old type of lego?
I hope the colour difference is clear in the pictures.
