And it went to a Very Good Home, too!
That's what I was worried about: that some CLOWN might get hold of it. I can stop worrying now!!
As to the sighting arrangement, I can't add anything except to suggest the possibility of the screw-holes being plugged. I have seen a couple like that, the work done in small shops after the rifles were surplused, likely about 1920, at the same time they were sportered. Not all Long rifles with shortened wood are the work of Bubba & Co.; many were done in small shops, given a refinish and a refurb. My own full-length Sparkie sporter is very like that; the other, which was interrupted on its way to the Pipestone Municipal Dump, has the holes but not the parts; it also was shortened by about 5 inches and that definitely was done by Bubba or his grandfather!
