I would imagine the Indian made blades would have a similiar or maybe slightly less value than the British made 1907 bayonets. Some of the Indian made 1907 style bayonet variations are rarer than others.
The British bayonets sell for anywhere from $50-$150...depending on maker, condition, etc.
Smokey Mountain Knife Works was selling P1907 british bayonets with scabbard for $25 a few years back. Supposidly in rough/ragged condition. ordered 2....thinking to double my chances of receiving a servicable bayo and scabbard. They sent me two perfectly nice 1915 dated bayonets in good scabbards. One a 1915 Enfield made bayo, the other a rarer 1915 Remington made bayo.
