The top one with the rusty bed is a Sears box-bed jointer from the 1970s. My first jointer was one of those. Probably a 113.3068 or 113.3069. The stock number will be on the tag.
The lower one is a Sprunger Brothers with an aluminum cutterhead. Likely older than the Sears jointer.
Given some elbow grease, new bearings, new knives, they should make serviceable jointers. I suspect that the Sprunger will need a stand and maybe a motor and switch.
No motor or stand is pictured for the Sears.
