Douglas,
I hate to do this since you have done a SUPERB job on your Mk 37 director, but I have to point out that the radar you have used is not the Mk 4 as used on the early FLETCHERS. The array you have in the center of the array wasn't used on the early Mk 4 and I believe was only used on the Mk 12 radar. The Mk 12 radar started to be installed in late 1943 on some FLETCHERS and a few months later the Mk 22 "orange peel" radar was added to the Mk 12 radar on the Mk 37 director. I only recently found out that the Mk 12 was installed without the Mk 22 (on BELL (DD-587) and a couple of others). You have a remarkable array here and I don't know what to tell you to do.
The model kit manufacturers have messed this up as well, DML has supplied arrays better suited for the Mk 12 radar for their BENSON-GLEAVES kits, however NO BENSON-GLEAVES unit ever had the Mk 12 installed. The BENSON-GLEAVES Mk 37 directors were the early tapered back type and there was no room for the Mk 12 radar.
