Hot Rods Shift knob

I need some help looking for a shift knob I had in high school. I looked through the shifter threads and didn't see any like it. They where long (6 to 8 in.) and tapered down. Hard plactic metal flake and sometimes came on a L shaped bracket to make them horizontal. I think i used to see them in big trucks mostly old trucks with 6&4 transmissions. Ive searched the internet with no luck. Anybody got a clue what I'm talking about?

 

Try a large truck stop. lot of goodies.

 

I went to Florida couple weeks ago. Stopped to look. Not many old Chrome shops left. Lol
