Got given this little lot today - pretty stoked. Ref 105.003-64, also known as a "Ed White", Pre Professional.
It'll be a lot of work, and I don't know if everything is there - but its always worth reviving a Speedmaster (I hope) I see new dials are still available - which is very tempting, and it has lost one of the sub dial hands
In between the rust and likely missing parts - this will be a lot of fun! The movement is a Lemania 321, and see new dials are still available, which is VERY tempting.
Wish me luck, this one won't be done in a hurry.
