Mike-
Zeke's last reply made me re-read your original post and your reply. Let me see if I can help.
As Jon says, there was no traveler on the 1963 boats, although the drawings I have seen indicate that by 1964, Pearson was supplying a simple traveler track with two stopper slides. The bigger point is that no one here will have any insight into how your boat was set up after someone put in a traveler system between 1963 and 1980, if that is the information you are trying to glean from the forum.
Over the last 60+ years, these boats have been rigged many ways by many people for many purposes, so there is no one way of doing things. That's one of the charms of owning an Ensign. It can be a blank slate if you want.
If you are trying to do anything other than replicate the set up you inherited, Zeke makes the important point: It's critical to know how you intend to sail the boat because cruising set ups are different from racing set ups.
On the other hand, if you are just trying to restore functionality and to reuse parts that you have, the good news is that you only need to be looking for parts that control the side to side travel of the traveler car. Sometimes that is as simple as a springloaded pin on the car or a stopper slide being placed into a hole on the traveler track.
Usually though there is a pair of control lines attached to each side of the traveler that move it from side to side and then secure it in the desired position. Most typically, the siezed end of the line on each side is secured to some sort of fitting at the extreme end of the track, fed through a block or sheave(s) on the car and run back to a cleat of some sort, usually a cam cleat. They can be rigged for 2:1 purchase, 3:1 purchase, 4:1 purchase or (although I have never seen this on an Ensign), even a 6:1 purchase.
To illustrate a pretty simple modern system, please see the following photo of the 4:1 set up on my cruising Ensign. The terminal fitting on each end of the traveler track is a cam cleat, a system that is common on Ensigns.
The system is sometimes reversed, with control ends of the lines at the car, like this:
To illustrate how different a racing set up can be, here is Harken's diagram of a 3:1 system for more precise control by a racing crew:
That's the concept and some illustrations.
Send some photos and I am sure you will get a response specific to your boat. This is a very helpful community.
