V.C.Schilling was, just like Haenel, one of the big Suhl makers of military and sporting rifles and M88 “Commission” actions. As these actions went out of fashion after 1900, their main business went down. So 47252 is certainly V.C.S. serial number. The resemblance to Mauser numbers is just pure coincidence. 754 is most likely the Poldi barrel blank number. The “lady” is the Poldi trade mark.
On scrutinizing the photos, I can make out the service load info: crown/N = smokeless proof, St.m.G. / 9 gr = steel jacket bullet up to 9 gramm. This speaks for the 6.5x54 k Mauser cartridge as the M-Sch load used bullets of 10.3 gramm. A M-Sch cartridge will not fit in a Mauser k chamber and vice versa. But the rifle may have been rechambered or even rebored much later in the USA as was often done to rifles chambered for unavailable ammo.
The rifle was certainly stocked and assembled at the V.C.Schilling factory, but sighted by or for VL&D.
The German imperial eagle above the crown/B mark is part of the proofmarks. It stands for the first proof.
