Manufactured in limited numbers by the Union Fire Arms Company, the Reifgraber was originally developed based on patents held by Joseph Joachim Reifgraber, a late 19th/early 20th century publisher who also invented a number of items, including advanced teletype machines. Fixed sights, with "UNION FIREARMS CO./TOLEDO. O. RIEFGRABER(sic) PAT." on the left side of the frame and "S. & W./32/CAL." on the right. Fitted with a back strap grip safety, manual safety, takedown lever and a pair of checkered grips. Two magazines are included, one numbered "38", and the other numbered "36". This pistol is pictured on page 288 of "U.S. Military Automatic Pistols 1894-1920" by Edward Scott Meadows, which includes a section discussing Reifgraber's attempts to attract military attention to the pistol.
