I have 11 adjustment handles for sale. I had one, but needed a second one. I couldn't find any for sale, so I took the one I had to a machinist. He agreed to make the handles, but I had to have a minimum of 12 to make it worth his while. He made them as close to original as he could. They have the correct size ball on the end, which as been silver soldered on and will not pop off. These are made out of solid steel and will not break like the original ones had a tendency to do. I had them painted flat aluminum, which looks close to the original. You can easily repaint them, if you prefer a different look. They are $55 each, including shipping (within the US). If you buy more than 1, it will be $50 per handle. I'd like to limit to 2 for the time being until I know how well this will go. I can have him make more for me, if need be.
Yes, I know there are only 5 pictured.
