Info for old Tommaselli controls

[Tee-Why]

Hi, my TY175 has be outfitted with Tommaselli controls and throttle.
I am chasing a replacement cover (clear with a small center fixing screw).

I may just being picky replacing this item, as I understand that Tommaselli is Domino anyway, should I just invest in a later version?

Levers, replacement items? Are they common to anything ie AJP or Magura etc? The split perch lever mounts are of good quality, a shame to replace these if necessary. Evil Bay search etc didnt reveal anything yet.
