I filled two steel tanks last week that were made in the 1970s....current hydro stamp.
Oldest one I've visually inspected was a steel cylinder born in 1962!
Tried to buy it from the guy just for the cool factor but he wouldn't turn it loose.
 
So far, I've only encountered one place that refused to fill a 6351.
One dive shop here won't fill any aluminium cylinder older than '88, even if its not 6351.
My hydro guy says DOT man told him to stop hydro'ing 6351 cylinders, so even if the shops would fill them, once the hydro is expired they're scrap.
