Adam...yes IMHO your drilling is a model 3000 Lux. The difference between a S53 drilling noted by Montenegrin and the 3000 Lux is that the trigger guard is made of horn on the Lux and it the Lux does NOT have CLAW MOUNTS for scope. the Lux also featured game scene engraving. Would really like to add these Drilling S/N's and related proof marks/info to my on-going Sauer research if you Sauer owners care to share. Please email direct if so. Thanks much...Jeff
