The Rectaflex series of cameras is apparently the only Italian SLR cameras ever made and arguably the first 35mm SLRs to use a pentaprism. The original Rectaflex came to market in 1948, designed by Telemaco Corsi, and enjoyed a production run lasting until 1958.
Several models were introduced, largely distinguished by serial numbers and shutter speeds. The Rectaflex 1300 was one of the last models made and true to its name, has a top shutter speed of 1/1300th of a second. The Rectaflex 1300 resembles most other 35mm SLR cameras of the time, using a cloth focal plane shutter, interchangeable lens mount and the aforementioned pentaprism housing that not only flipped the image right side up in the viewfinder but corrected it left-to-right as well. This now-standard feature on SLR cameras was virtually unheard of at the time of the Rectaflex's introduction.
These cameras are extremely uncommon, and likely are just collector's pieces as they will probably be in non-functioning condition when found.
