Must be getting close isn't it due out this year?
Mid 2015 originally but that info has now been removed.
(Correction to my earlier comment. I incorrectly mentioned polishing 'chrome' armour, yet pins have only ever had 'stainless steel armour'. I was thinking stainless steel. It's the Legs have been chrome.)
I thought legs were nickel plated from factory?
Chrome has a more "wet shine" look than standard SS polish. Good for a showpiece machine in home use but not all that practical for a commercial environment particularly the lockdown bar which theoretically will have heavy contact onsite.
Double correction it seems. Yes, nickel plate sounds right for the legs, rather than chrome plate. Same process - they are both a thin layer of nickel or something electrically added to the metal legs. Nickel is reflective but has more of a dull 'matte' finish, while chrome has a 'full gloss' mirror finish.
both plates are not as resistive to damage and repairable as the stainless steel armour. That is probably why legs transitioned to 'black', while armour was still stainless steel.
(I think I got that all correct!)
