Manufacturing Mistakes on Original Parts

[Keith True]

I have an NOS worm gear and shaft,NOS sector housing,and a NOS sector for a two tooth box.I got them in the 70's,they came from the South Weare Garage that was a Ford dealer in the A era.I saved them for years,and about 5 years ago I built a steering box with them to use in my pickup.I have NEVER been able to adjust that box.When I finally took it apart and started looking I found the sector machined incorrectly.One tooth is off,the teeth are not parallel with each other.It is off enough to see by eye if you are looking for it.When compared side by side with another sector it really shows up.I also found the shaft and worm are not straight,but I attribute that to the part being leaned on a wall and knocked over dozens of times in the last 80 years.It also has stamps and labels all over it showing it was shipped from dealer to dealer with the last date being 1949 by REA.
