Are all DONs created equal?

Calling all #Speedyheads

Are DONs that were originally installed with various Speedy references starting from the 2998s down to the transitional 145.022-68s exactly identical and interchangeable?

E.g., Could a watch with less than perfect dial and movement shots, but an excellent bezel, say a reference 2998 or 105.0xx, possibly have had a bezel transplanted from a later 145.012 e.g., that is slightly more plentiful?

Is there any distinction in the bezel fonts etc., that can help visually identify DON bezels from different references as such.

I know of no differences that would date them.
So completely interchangeable.

As I recall from possibly @Archer, some fit better than others. As far as a reference, Moonwatch only. Speedmaster 101.
