Do you recognize either of the below Lego sets?
We received them as a hand-me-down gift with no instructions.
Thanks for any help!
Top set is indeed 75013 as per @lego-related username's answer.
Bottom set is 75024 HH-87 Starhopper.
Top set is number 75013, Umbaran MHC (Mobile Heavy Cannon). I think the previous owner modified the cannon, because the actual set looks vastly different up there. I don't recognize the bottom set, but it looks like some star wars set.
The second set is 75024-1: HH-87 Starhopper
