It's a works 93 but is missing the torque stay that fits over the steering bellcranks and the turn-buckles that fit between the c carriers and the stay. Torque stays come up from time to time (fibrelyte do them) but you rarely see the ball that fit on to the stay, the turn-buckles are very rare if you need to replace them, the part number ZC 209c. The bumper is a RPM one, original yokomo bumpers are almost impossible to find.
It's also missing the battery posts, again very difficult to find.
Here is mine
