Flightmaster 145.026 NOS Casbeack

I recently bought a NOS caseback from ofrei for my flightmaster. But i recently learned that my FM was an 145.036. I am therefor selling my 026, and looking for a 036.

I can PM you pictures, but the caseback hasnt even left the plastic cup from ofrei - its untouched mint. Bought it for 279ish $.
