Nissin Front Brake Master Cylinder

[MightyDuc Racing]

I have a Nissin front master cylinder with 2 levers for it.  It's in great shape, but has a different thread pattern than my Brembo one.  It has been in my box as a spare and was on the bike for a while before I got it, but I'd rather have two that are exactly the same so swap time is quicker at the races.  Any idea what bikes it will work for or which one it may have been originally designed for?  Anybody need one?  Help....TIA.

Send me a pic of it if you can.  I may be able to help.
