I'm not sure what the spring that I found in my spares box was for - old BSA or Webley most probably, But I fitted it and it feels just right - not too strong or too weak and shoots very smoothly so I'm happy to carry on with that.

If anyone is reading this in future, the Gamo 68 & Gamo 85 Paratroopers (certainly the ones that I have ) do appear to take different springs and the Titan XS No.13 is only good for the 68.
