Complete Omega 1861 or 861 movement

Hi OF

Have a project that I need a new movement for. Per title, looking for either an 861 or 1861 movement in good complete condition. Service history is not so important as long as it is complete and in good physical shape, no partial movements or rust buckets. A "new" service 1861 movement is ideal but I can take an 861 that came out of a Mark II or something similar.

(Yes, I know Swiss Watch Spares has service 1861 movements for 1400 GBP or so but thought i would try here first.)

Thanks OF for the space, and thanks to all members cruising the WTB section.

Still looking 😎

Also open to an mkii or deville chrono with an 861 but prefer just a loose movement if available.
