Examining the tefiros and matleisim at the seams, it is obvious that the yerios were put together a very, very long time ago. This is true even of the places in which yerios are missing. So.... over 100 years ago, someone assembles a 2/3 finished sefer torah and it has been making the rounds at shuls since.
At the owner's request I am trying to assemble some more insights into this eccentric debacle - could the chevra please take a look at the photos and offer opinions as to style/locale of the ksav, the name of the sofer (the first line, Menachem Mendel, is obvious, but the second line is harder to make out), and if anyone has ever come across anything similar.
