The more I read the more confused I become. Does anyone know if Chapuis made a single underlug SxS in the past and if so when. I bought mine used and the person I bought it from said he ordered it new. It came with snap caps made from cut off RWS brass that I believe were made by gunsmith at Importer. If memory serves me it was engraved on rib under forearm "Champlins Firearms" in script. I removed the scope base filler blocks from rib and replaced with custom Ruger blocks using same screw holes. Had to use high rings though cause you couldn't get to lever with low rings. Thoroughly likable rifle. I really miss it. Shot wonderfully. But there was this Heym 375 I just had to have.
