Schmidt-Rubin M1889 & Austrian M1886 Mannlicher rifles

Can "any-buddy" direct me in getting 'exploded views' of these 2 guns?? Also a source of parts for Swiss S/R m1889, I especially need the magazine locking lever (Numrich calls it a "cut-off", but it simply retains and releases the mag from the gun). To me a 'cut-off' is what a turk mauser & an early SMLE has...the swiss part LOCKS the mag into the gun.....Steve
