Bought a speedmaster from William (Spacefruit) it was a pleasure to meet with him in person and complete the deal. Excellent item as described from a forum member who has an excellent reputation that has only been +1’d from my experience.
Basically, it comes down to this: if William has a Speedmaster to sell, and you can afford it, buy it.
Based on my own personal experience, I can wholeheartedly agree to the above. +1. Highly recommended as a seller and great to have a chat with as a fellow Speedmaster enthusiast.
