Recently I've been working on a similar load on a Gotz hammer cape for hunting buddy. Ford is always most helpful and may have penned an article or 2 in a GGCA publication. Also I think the firm P.(Peter) Oberhammer is still in business, maybe in Kln. It appears to have Austrian type features and interesting how the locks do not interface with the frame.



Kind Regards,
