GECADO Belgian sourced hammergun

True the tubeset has most of the info but there are marks on the water table that typically provide direction for a maker origin/gunmaking centre. Here on the action in question the star is one of the 1st clues(I'd say it surmounts a letter not a number) and the Perron is the 2nd. And for the most part the marks are location sensitive at least for a particular time period.

Kind Regards,
