Helping a friend with some guns. I believe this a a custom gun by Nicholas Lardinois of Liege. The gun has been seriously mucked with. The last 6 inches of the stock have been repaired/replaced. The gun has been relined. One Lardinois mark is on the barrel flat as pictured. There is no Liege proof I can find. The Lardinois stamping on the right side barrel flat appears to be an over stamp. The same stamping is on the underside of the barrel, though it is not an over stamp. The C Pfafff may be a sewing machine manufacturer in Germany at the time Lardinois was working. My assumption is this is a custom sporting rifle made for Pfaff by Lardinois. The gold work, trigger guard and the engraving seems typical of other Lardinois guns. Opinions and information please.
