Thanks for the effort, J.B., as I know it takes time. Typical Rigby style forend latch and I think it to be reproofed, for want of a better term, post 1912. Heinrich Scherping may have made this one himself or contributed to the effort. Although it may have been made post 1912 of older components but there was a lot of hand effort as seen pre-WWI that was pretty much extinguished post WWI simply due to the loss of craftsmen, loss of market(Austo-Hungarian empire was divided) and mechanization taking up a large portion of the gunmaking task, or components being sourced closer to the finished state.

Mr. Halliquist:
Even before the ref/pics, I wouldn't think the tubes to be pattern welded as in the 1870s and 1880s the Germans thought they wanted to be English and then I believe they found there identity at home and began colonization. But many higher end examples were fitted with early British fluid steel tubes.

Kind Regards,
