Speedmaster 145.022 - Caseback and bezel, interchangeable?

Hi,

I recently purchased 1988/1988 145.022. Unfortunately the case has seen some bad polishing and it´s technically ruined - it will do for now but some point I want to get watch back to its former glory.

Managed to find a NOS 145.022 (Mid case) and the plan is to do the swap in the next service. My current case is manufactured by KB (based on the caseback). The NOS case manufacturer is unknown since it does not have a caseback.

What u guys think? Will my current caseback go on its place without any problems if the NOS case is manufactured for.ex by C.R.D. Same thoughts about the bezel?

Thanks in advance

Thanks. I assume that tolerances are small and we are not talking about 1mm differences, different threads etc. So I try to stay positive and say the swap is doable... 😀
