I recently acquired a few pounds of LEGO with some off-brand building blocks mixed through it. I've got three mystery pieces that I haven't been able to find on Bricklink. I'm wondering if they are Lego or off-brand pieces. I was under the impression that most LEGO pieces had the word LEGO written on them, and none of these do.
I'd like to know if these are Lego pieces. Reasons that they likely aren't (eg. LEGO has never used that color) are great too.
