Sorry guys, can't find the answer via search, but what is a
parallelogram stick?

This is one, in a Club Libelle.

Sorry if it's not too clear but I wasn't especially taking a photo of
the stick!

The stick grip is on a vertical shaft that comes down only as far as the
horizontal tube, to which it is rigidly welded. There are two pivoting
vertical tubes coming down from the middle and front of the horizontal
tube. The front one is obscured by the foam.

That looks quite similar to the Mosquito stick, which uses a vertical
leaf spring as the front support for the parallel tube. IOW the leaf
spring serves as both front support and as the trim spring.
