The number of NSX variations issued by Tomica is quite high - second only to the S800 as far as Hondas go.  Tomicas NSX's are 1:59 and with varying levels of detail varies depending on the issue.  The NA1 NSX's were issued as No. 78 (including the NSX-T), followed by the NA3 as No. 81. The NA1 Safety versions with light domes are a variation.
