Nick Van Vonno in Melbourne, Florida finally located a S.659/670 to replace the one he let get away a long time ago. It was shipped from UK and arrived in pretty good shape, but one of the handles was broken off.  This involved breakage of both screws, which Nick considers was  a carefully thought out way of limiting the damage to the front panel. The handle on Nick’s set is not damaged, however he can’t locate the two brass replacement screws so is appealing for help from the Eddystone User Group to find him some.
