 All, please excuse my ignorance...which models had a vented hubcap with the additional screw-down fixing?

 Pretty sure they're from a Silver Shadow.
 The bolt hole was an option, but I'm not exactly sure how it was implemented.

 "Pretty sure they're from a Silver Shadow."
 
 I once had a Spirit with that feature. The hole is occupied by a bolt with "Security" head with a wavy-line pattern impressed into the head and a corresponding key to engage it.  There is a threaded boss welded to the wheel pressing to suit. I assume it was also available on Shadows???

 Thanks, I see flying spares offers a locking screw kit and key for later cars... i only saw this once on a '60s Phantom, and there it looked slightly DIY.
 As you say, it could be an option for those driving in less salubrious neighbourhoods...

 My 1975 Shadow has the hubcap locks, as described by Alan

 It's just occurred to me that if a previous owner lost the tool to fit the bolts it may have been expensive or difficult to get a replacement.
 Are they all the same "code"???
 Are there screwed bosses on the wheel disks?

 Alan YES There is welded boss on the wheel that the screw goes into and a finger on the inside of the hubcap right next to the valve stem hole that matches a hole in the wheel to help line up the hubcap upon installation.
