Got a couple saws at auction (First Time!)

[Doug]

A Mac 10-10 auto, complete and fairly clean, A Skil 947 top-handle, appears intact, and a vintage Husky 61 parts saw. The 10-10 was very stiff to pull over, even with the plug out. Squirted some WD down its throat, seemed to help a little bit, but still way too stiff. No idea what that's all about. And the little Skil same thing, just seemed way too stiff. Is this normal for a saw that has probably been sitting for a very long time to do that? Is there a cure? Am going to try to get the 10-10 running, but the Skil and the Husky are just surplus. Any idea if they're worth trying to sell? Not much market here in Anchorage, and the only practical way to ship outside (from Alaska) is if I can take it apart far enough to get it in the 12 x 12 Flat Rate box ($25).
If there are any other Alaska folks here, please reach out to me, I'm a newbie here, and need all the help I can get
