I assume the trigger block was changed thats if, as an improvement over the early trigger units.
Although you have the gap for a tang on the trigger guard area on the stock, how do you know that the stock is a replacement, the original stock broken. With the trigger block and cocking lever of a standard, i would be more inclined to think the stock is the odd one out, although both light pattern and standard stocks are similar in shape.
