145.022-69/71 Speedmaster case and -back + A2 crown

Hi all,

Having fallen for an attractive 145.022-69 Speedmaster dial, trapped in a rather overpolished case, I am on the lookout for parts. Please shoot me a message if you have any of the below and are willing to part with it:

- 145.022-69 or -71 case in good vintage condition. Certainly doesn’t need to be mint! Pushers and plexi would be a bonus.
- 145.022-69 caseback (standard Seamonster)

Lower priority:
- A2 narrow angular feet crown
- 145.022-69 tritium hand set is welcome too…

Thanks in advance for your reply and of course thanks to OF for this space!

Looking forward to reviving a slightly abused Speedy together. 😀

Some helpful responses already, not yet found the parts I am looking for.
Thanks to @ndgal 's great case study, I can widen my search a little. A midcase of either a -69, -71 or early -74 would work!

Update: Caseback no longer needed. Still interested in any hints leading up to obtaining the midcase. 😀
