Razor first gen spotting scope focal length? (2 Viewers)

Just bought a 65mm first gen razor spotting scope,and a Swarovski Astro adapter. I have a few eyepieces was just wandering what the focal length is?
 
The zoom eyepiece on your scope is an exact copy of the 20x60 Swarovski zoom. It has a focal length of 7.7mm at 48x and 23.1mm at 16x, so the focal length of your scope is 369.6mm.
