Were the early drag links (1909/10/11) the only ones threaded at both ends and were they fine or coarse threaded?
The 1909-1910 had a threaded drag link with a 20TPI thread and locking nuts at both ends of the rod. In 1911-1912 the thread change to 13 TPI, and in 1913, the three piece drag link had the forged ends riveted and brazed to the rod.
I hope this helps,
Thanks, Russ, indeed it does!
Bill, Russ's reply may have missed a point. The drag link on my 1912 does have the coarse thread, but it has the adjustment at one end only. The other end is riveted and brazed, just like the two ends on the 1913 type. I don't know if this is true for all, or just an interim application.
