An AAV works in your house because the system you are draining into has a main vent. This lets sewer and fermentation gases escape to the atmosphere. Without this vent, gases will vent by blowing the water out of your P-traps.
The correct aluminum to match the original is 2024-T3 Alclad, 0.32". It will not look llike your current skin because the skin has oxidized for almost 50 years. It will match if you polish the existing skin.
OK, so I'm off a little on the aluminum. Probably best to use 0.032" thickness, rather than 0.32".
Here is how I did the vents on my '59. The vent is from VTS, the gasket material is fiberglas reinforced red silicone and the screens are a tea strainer, both from ACE or True Value.
