From the rear side of the end plate that retains the inner mag to the rearward (back) of the ring at the rear end of the magazine is 24.150". From the same location to the forward side of the ring is 23.950". The ring measures .200 front to back. Hope this is useful.
Many years ago bifocal lenses were made for pharmacists who had to read labels on high shelves. These were made with the reader lens at the top instead if the bottom.
You could do as I have done and get a pair of these made with the focal distance at +.75.

The G&A pin and Hornet cases look like they were done by a previous owner. The repair around the pivot screw area quite likely done in the US. I have seen a fair number of Swiss and German single shots over the years that were made by individual makers that had similar styling but the actions...

It is a Swiss or German built Martini style action sporting rifle made pre WW2. There were many individual gunmakers in that era making similar guns. Not a Farquharson, the big screw at the top rear of the receiver is the pivot for the block. Because it is not a factory built rifle parts would...
