Hi,
can anybody comment on the old pneumatic pistons, those in
e.g. 8851? They seem to have only one connector, so it
seems that you can only push them out, not retract them like
the new ones in e.g. 8462. Or is there some spring inside
to contract them?
Also, has anybody a list of sets with the small piston/pump?
I only know 8868.
Greetings
Jürgen
