So, I have a 105.012-66, which I love, but it is with a 145.012 movement. Hoping to see if anyone may have the same issue in reverse, or an extra 105.012-66 movement they are willing to trade. I will be offering cash in addition to the 145.012 movement. Cash will be dependent on condition of the movement and if a service was done recently. The 145.012 movement offered is clean, working extremely well, and will come with Archives verifying it is from a Speedmaster. However, no service history is known. I will share pictures with anyone interested. Thank you OF for the space!
