G. Wilcke owned by Mr. Hallquist, so let me rephrase my 1st post in that the "HK" may be a control mark if, if "EK"(Emil Klett tube maker post WWI?) and/or a "K" in a rotated square/rhombus is found on the tubes.
I have a guess on the trade-guns and it may be that the firearms merchant ordered more than he purchased so they didn't roll stamp his name on the tubes on the tubes or top rib.
Yeah, pics of the action, either right or left side, & underside. Any pic better showing the area between the flats & forend lug.
Kind Regards,
