The V crown guard was an G-current series rep crown guard that a member of the community, V, produced... there was one run of them and they can only be found in the aftermarket.... currently, they go for between $200-350 depending on condition and aftermarket work/finishing... they sold originally for $200 each...
They are the best option for an G and new Panerai rep.... other than a gen CG of course... not perfect but very, very close...
They only fit the standard rep and newer DSN cases... they will not fit the older DSN cases....
To find one, you will have to put out a WTB or wait for a member sales ad...
Here is a pic of one I had before in a side view... prior to refinishing...
