Nope. Didn't see anything like it - it's probably too old to still be made.
So, at a local Trash and Treasure sale, I rummaged through a box of hoarded hardware that somebody's wife MADE him give away. Wow, a Warlan No. 1a Pneumatic Door Closer, exactly what I wanted. It had instructions and all the screws in a sealed envelope. $5 please, including all that other stuff you are buying.
And today Jeff and I installed the new door closer. Sigh!
