My buddy found a Case Tested yellow handled jack. Can someone help me with the pattern number? Thanks for the help!

its 3 and a quarter inches long.

At 3-1/4 iinches it would be an 087 pattern. Probably a 42087, sometimes the white synthetic/celluloid covers turn a yellowish color with age. None of my references show a 32087 from the Tested era.

Thank you Ken! Steve identified it as a 42087 as well. I appreciate you both!
