55.2-59 Attn Navy veterans or historic USN vehicle buffs

[Patina.au]

Hi all. First of all, to all veterans and families, thank you for your service and sacrifice.

Quick overview. I purchased an ex USN 1957 3100 out if the Pheonix area (from the third owner) that had been sitting for some time. After its navy service, it was owned by Paradise Valley District as a maintenance vehicle. Mileage shown is 40,000 which is believable based on condition. I need help decoding the navy department plate fitted to the door jamb as I want to restore to original externally with color and signage/markings. Under the white paint is the original Battleship grey covering everything - grille/bumpers/headlight surrounds. Anyone with info, historic photos, font type or size that could share would be greatly appreciated.

Cheers, Neale
