Looks like a #3-5 Hunter model from the mid 1960’s through early 1970’s (‘64-‘72); the stone, if any, could help narrow that down. You said knives, but I’m only seeing one. Hope that helps.

1st and 3rd from the left fall into the original dates given, 2nd from left is mid to late ‘80’s, 4th over is new enough to be considered current production, and the mini #3 on the far right was early 2000’s if I remember correctly.
