So it's Trans Silver somewhow?
Is the V grain from being a center joined 2 pc body?
The way Epiphone supposedly shot the Silver Fox finish (which seems to have been a color option for about 5 years in the early/mid '60s) was to start with a black wash/stain, then apply silver grain filler, and then nitro...a process similar to Gibson's original TV Yellow, just with a different color set. When these guitars shipped, they were (again, supposedly) black and silvery white, with the finish referred to as Silver Fox because the overall color pattern resembled the pelt of that animal. I've been looking for years for a color photo example from that time to attempt to confirm the original palette of these Epi guitars, but have never found one. That said, the recent Gibson Custom Shop "Brian Ray '63 SG Silver Fox" is definitely black and silver/white.
Over the 50+ years since these guitars were made, the black wash has broken down to a more blue/blue-black color and the nitro has ambered, resulting in the myriad green hues of their current finish...depending on the lighting these guitars can appear from nearly kelly green to dark olive, and pretty much everything in between.
My S-100 was shot in a similar matter as those '60s Epi's...we just tweaked a few things because I don't feel like waiting 50 years to get that effect.
Regarding the V you reference, that's just the body's grain pattern. It is definitely a single piece of mahogany.
