All I can say is this. I have a console and looked hi and low for long knobs for my original AM Philco radio. Finally, Brian B. came through for me for some and I put them on. However, the long knobs stuck out to far and looked like they did not belong. I put on shorter ones that I had and they worked fine.
I can not explain it but that is what happened..as close as I can remember.
