Welcome!
Your "new" lathe is very versatile bit of kit.
I modified my look-a-like machine by making and fitting a 80T gear to the input of the Norton box, to halve the feed rate. Mine is Metric with dual dials. Yours could be Imperial or Metric, Warco offered both versions..
On mine, the setscrews clamping the Top Slide were pretty soft and were soon replaced.
17 years on, the original belts are still in good condition.
If the secondary belt does need replacing, Roger Warren advised against stripping the Headstock, but to cut off the old belt and replace with link belting, to avoid disturbing the pre-load on the bearings and the oil seals..
The chucks, especially the 8", 4 Jaw are heavy, so a wooden chuck board is an early accessory to make.
FWIW, avoid clashing the saddle with anything, when under power feed. The shaft and the integral pinion engaging the rack is adequate for normal use, but not of high grade material. It bends easily, as I know to my cost!
At one time, I thought that the belts were slipping. The problem was too shallow a dimple in the shaft that carries the belt tensioner. Soon cured, but not a lot of room to refit the bolt between the lever and the link.
The bolt clamping the Fixed Steady needs to be the made captive, to avoid frustration..
But, overall, not a bad machine
