Can anyone identify this joystick??

I have a mini neo candy and I can't seem to identify the joystick maker. I am assuming it is Sanwa but wanted to see if anyone can identify it for me. I am trying to find replacement joysticks but I am having trouble. The mounting plate is square and the mounting holes are all 5cm apart.

It's a Seimitsu.

Thank You MKL. Any idea where they can be had? Or similar replacements?

If you want to identify the exact model check the code somewhere on your stick. It should be LS- followed by some number. Here's the current Seimitsu catalogue:
