Help wanted in sorting out a BSA Cadet Major for an old boy of 80 who asked me to repair it for him. The sear won't hold and it looks like the trigger and the piston need replacing due to wear. Does anyone know where I can get reasonably priced parts from (including possibly a complete gun for breaking as spares) as the gun isn't worth a great deal and the old boy hasn't got any money anyway. Any help appreciated,

Vic Thompson.
