I have 3 Dorflinger air pipettes that I no longer need.
1 was attached to an 38-Ar spike for 30+ years. (I think I lost the
spike when I was moving the bench).
1 was attached to an Air spike for 20+ years.
1 is brand new and fitted with pneumatic valves.
If any one in interested please drop me a line.
