Hi Hunter,
the Sumnerīs all looks different.
It is not easy to decide wich bridge you should use cause there are so many different pictures in the net.
For example here are pictures from the USS DD -727 De Haven with the old bridge.

So what is truth ?
Your Version of the painting ore the version of the model ?
In the moment iam workin on it an my opinion is that i will bring the Sumner with the open old bridge and the Smith with the new closed one.
So you got bothe version of bridgesystem.
Regards
Maddy
