Serial Nr 164004.  Professional looking job, long ago, for target shooting.  Barrel shortened to 24".  Turned down a bit to accept 1903 sight and muzzle crowned.  Lightening hole in fore end filled as is handguard.  Lyman 48 rear sight.  For the rapid fire stages used tar tape to hold the five rims in alignment, close the magazine on them and pull out the tape.
