A beautiful gun Ivo. I can only echo the comments already placed here, but what about those indentations on the barrel surface? This type of indentation has been discussed elswhere in relation to Rick's Tanchika

The suggestion is that at some stage these held stones/corals as decoration. There appears to be residue in the indentations on your gun, so what do Members think as to this being some sort of glue which originally held stones in place?
