Can anybody comment on this SP-600 with a nickle plated front panel? I had one of those several years ago (now in the collection of Ross, W1EKG), and this is only the second one that I have seen.Who were they made for, and why?Any idea how many were produced?Inquiring minds want to know!Chuck N1LNH
