That's an Indian made No1 MkIII* that has two extra holes drilled in the receiver for a scope mount, during the sporterizing process. Negates any collector value.
The round hole on the left side of the receiver ring is a war time vent hole.
very interesting, you sure know your stuff, matter of fact, i bought this gun from an indian fella, but how did a gun from india made it to Canada.
