Concerning Rigby guns and rifles for the period of 1890 to 1914 -
Actions came from Osborne, L&L Pryse, Webley & Scott, P. Webley & Son, Saunders, Bentley & Playfair, Ellis & Son and others.

Their Best guns and rifles (until about 1906) were made on their vertical bolt actions (rising bites). Four "workshops"- Wheeler, Phillipson, Hill and Wall were the "barrel filer and actioners." There is no surviving information (that I am aware of) that establishes Rigby provided those workshops with forgings.
