I have a surplus and rare Losmandy machined 21 pound counterweight. Has a few chips but could easily be made to look new with a light sanding and crinkle-coat paint.

It has a centre bore of 1.5" with a threaded offset for use on both smooth
and threaded counterweight shafts.

A new Losmandy 21lb weights are castings and are no longer machined. They will set you back $250.

Asking $100 or reasonable offer. Pick up preferred, as postage I suspect would not be cheap. (I'm in Sydney's south).
If you are interstate, any postage would be an additional cost and vary with your location.
