In the middle is a single integrated weight-set from a 3009 purchase. This has only the basic vtf weight attached (note the coupling sleeve).

* wayrod - the "L-shaped" thingie that holds the small weights.

Notice that one is a 'through-hole' whilst the other is 'closed-end' at the rear of the counterweight.
