Would you use a homemade crib from the 80s?

.

I am a First time mom and my mother in law mailed me a crib (must have cost a fortune to ship) that was handmade by my husband’s grandfather when he was a baby. My MIL wants us to use the crib bc my husband and his brother and cousins used it when they were babies in the 80s. I am worried about the safety of it.. I don’t know anything about cribs bc I’m only 3 months pregnant but aren’t cribs safety rated? Is it safe to use a handmade crib? Would u be comfortable using that?
