Hi, Clark,
Thank you (and to other posters) for all the wonderful ideas and
advice. I'm 99.9% sure the slopes and columns are LEGO parts, as were
two of the tiles. The others were third-party.
Best of all, I satisfied my own curiousity and found new resources for
research. Thank you, thank you!
And now, I just need to resolve the 1 pound 2 ounces of non-LEGO parts
with the seller; I'm willing to eat the shortage, as the term "over" so
many pounds is rather vague. The seller hasn't replied yet, but I'm
just asking a straight exchange weight for weight. Next time, I'll
make sure to purchase from someone who seems more a "specialist" in
LEGO parts.
If the seller doesn't resolve the issue, I may just donate these third-
party pieces somewhere and post negative feedback. The actual LEGO
parts were quite interesting. I've gotten quite a few useful parts for
class and a bunch of parts for my daughter and me to build with. (I'm
just chomping at the bit to hear from the seller, because I don't want
to mix the new parts with "mine" until the issue is resolved.)
Thanks again to all who replied for their excellent advice and help.
