Missing Knob on Door Vent Window

Question

Hoping you can help me locate a replacement knob on a kitchen door venting window.  House was built in the late 40's, and I'm assuming the door is original.  The knob clearly has the letters "BA" stamped onto it.  I've tried unscrewing one of the other knobs to determine if it's threaded in (perhaps I could match thread size and replace all 4 knobs), but the knob just turns and doesn't come out.  Any assistance you can provide is appreciated.

Thanks for posting. I am afraid we don't carry any part like this. A local hardware store may be able to proffer a solution. Sorry we can't be of more help, and thanks for considering our business.
