That is one of the old Webb Design stainless airboxes. They were made in central fla. back in the day, i installed a few and they were very well made but had a draw back or two including they would still occasionally pop the welds on a backfire even with the built in pop off valve.
The other problem we ran into was that they did not make them for the very first small port CIS systems so when installing on a 73.5 or normal 74 you had to find the reducing sleeves that you see on that box. The boxes also got very hot in stop and go traffic in south fla. heat.
