How peculiar. Perhaps a Wal-Mart-only special run? The "10" (whether 110 or just 10 for long vs. short action) has always meant wood in the past. "10" means wood, "11" means blue and synthetic, "12" means laminate, "16" means stainless and synthetic... you get the idea; the numbers are the code for what they are (the letters help code further). Savage's current product line at their website and printed catalog both still verify this.

The number designations are as follows:
(this was taken from another website)
12/112 or 10/110 - Varmint/Target series...only drilled and tapped for scope mounts, no open sights, 24" or 26" barrel, blued or stainless depending on specific variation
11/111 - Hunter series...open sights & drilled and tapped for scope mounts, 22" or 24" barrel, blued only
110/111xxXP3 - Package series...no sights, comes with 3-9x32 scope mounted, 22" or 24" barrel, blued only, wood stock/leather sling installed or synthetic stock/nylon sling installed
16/116 - Weather Warrior series...no sights, only drilled and tapped for scope mounts, 22", 24" or 26" barrel, stainless steel only
The letter codes are what determines the "specific's" of the rifle...here is the list:
AK -Adjustable Muzzle Brake
B -Laminate Stock
C -Clip (Detachable Box Mag.)
F -Synthetic Stock
G -Hardwood Stock
L -Left Hand
LE -Law Enforcement
ML -Muzzleloader
NS -No Sights
P -Police
SE -Safari Express
SS -Stainless Steel
U -Ultra High Lustre
V -Long Range (Heavy Barrel)
XP -Package Gun
Y -Youth
so...the 12FV is a short action model with a varmint/HB and a synthetic stock!
Hope this helps clear things up!
