Your rifle is a sporterized No 4 Mk I. It appears to be a standard English made wartime production rifle, which has been extensively modified. The wood has been cut back, the barrel may have been shortened and has a new front Parker-Hale ramp on it, someone has taken a grinder to the charger bridge to remove half of it, and the left side wall has been drilled for a scope mount. If the bore is good it should be a good deer rifle, but it has had too much done to it to restore to original military configuration. Not sure what they are worth in your area, but in my area, about $150.
