Aluminum tank valve

[Daved222269]

I’m looking at a picture of a used aluminum 40. It appears to have a slanted valve on it like an old 7/8 Sherwood style. Could that be possible? Did aluminum tanks ever have that neck size?
Or is it just an older, different valve on a standard tank? I’m hoping to look at it in person this week. Thanks.

they made that slanted valve for standard 3/4 valves as well as the 7/8 valves. I have probably 4-5 AL40's that came with them when I bought them

Thanks for your help!

Those handwheels make me think they might be Genesis valves. Service parts are a little harder to find, and a bit more cost.
