Looking in the box the keyboard came in - it’s an IBM Model F. It’s packed in the original styrofoam.

My favorite e-waste place (Earthbound Recycling in Eureka MO - I don’t even live in the state but I go when visiting family) has an in-box IBM 5150 with MDA monitor and keyboard. It looks like the bottom tier spec one that doesn’t even have floppy drives.
