Who made my Verney Carron 475 No.2 Nitro Express

Hello Folks,

I recently acquired this 1929 Verney Carron 475 No.2 Nitro Express Double Rifle. I'm wondering who really made it.

Here are the specs:

Verney Carron .475 No.2 Nitro Express
Built in 1929
Weight = 10 lbs
LOP = 14-3/8"
Barrel Length = 25-3/4"
Rear Sights = 1 Stand 2 Folding on Matted Quarter Rib
Extractors
Hinged Front Trigger
Chopper-lump Barrels
Rib Extension with Scott's Hidden 3rd Bite
Reinforced Frame
Bushed Firing Pins
Reinforced Comb
Unknown Letter Monogram on Bottom of Stock Behind Grip
Unknown Silver Crest Inlay on Bottom of Stock
Silvers Style Red Recoil Pad

Markings as follows;

Left Barrel Top marked - .475 No.2 Nitro Express - Cordite - 85 Grains - 480 Grain
Right Barrel Top marked - Verney Carron - Liege
Both Barrel Bottoms marked - .475 No.2 Express - B.BLINDEE
Left Barrel Bottom marked JF - with Eagle's Head Stamp (Jean Falla)
Left Side Action marked - Verney Carron, Liege
Bottom Rib under the Forearm marked - 500 GUNS INDIANAPOLIS,IN
Various Belgium Proofs with an h 1929 Date Code

Either this rifle was hardly ever used, or incredibly well cared for, because the action is tight as a Bank Vault (so tight it takes an effort to open and close) and the Chambers and Bores are Mirror Bright. Close examination shows period Re-Blackened Barrels and Cleaned Action.

I've made contact with Verney Carron in France with the help of Ken Bush, who has forwarded pictures in hopes that VC may have some additional information. However, it is somewhat doubtful because most all of their records were lost during WWII. If nothing else, I'm hoping to find out if this rifle was "made by" Verney Carron, and proofed in Liege, or if it was "made for" Verney Carron by a Belgium maker. Or perhaps Verney Carron had a sister Company in Belgium.

As always, your comments and insights about this rifle and its markings are most welcome. I would especially like to know if anyone recognizes the Unknown "Letter Monogram" on Bottom of Stock Behind Grip, or the Unknown "Silver Crest" Inlay on the Bottom of the Stock.
