Bomber vs Clipper differences and serial number change.
 

What are the differences between the two other than the speaker grill image?
I have one of each on the bench and observed the following differences:

Clipper
Greenish croc scale highlights
Two piece lower latch (the part that gets captured by the bail).
A thicker bail


Bomber
Reddish brown croc scale highlight (no pic sorry)
Single piece lower latch
Thinner bail.

And what serial number did Zenith change to the Bomber image?

And I still have not come up with a viable reproduction simulated Croc
covering.
