Hello I have basso lotto slx frame it came with ultra torque cups I am going to convert back to record tapered system does any know if the frame has italian thread on bb.
 
No idea, but just measure the shell width. if you are still unsure and want to find out before removing the DS cup so you don't turn it the wrong way and tighten more instead of loosen, just remove the NDS cup and measure it.
 
As Foz said, measure the underside of the shell - 68mm is Birmingham, 70mm is Italian. That seems the easiest way to me.
