Gene, I am not aware of any 81 models WITHOUT a telescoping column, but I am not an expert on this. I read the selling ads on eBay EVERY day to see whats out there, have not seen an 81 yet without the tele.
Just underneath the horn button is a small tab. If you are looking at the horn while in the drivers seat, you should see this tab at about the 7 o'clock position. Slide the tab upward to the 10 o'clock position and you should be able to pull, or push the wheel down/up. Once in the desired position, push the tab back down to lock it in the desired position.I hope you can understand this description as I know it's not that clear.
Again, I am not an expert, but I do think all 81's came with this option. Perhaps someone with more knowledge can chime in here,
Merry CHRISTmas everyone. Mike J.
