Yup, its mine.

If it has an octagon-shaped yellow handle, with the SNK "double S" logo on the top, it is the exact controller.
Other things to look for:
- On the bottom of the rotary part, is should have the "double S" logo and "SNK Group" written on it.
- Black microswitches
- Yellow microswitch mount
- 13 pin rotary harness
- rotary housing is half black, half light green.
Thanks!
