how do you differentiate a no1 vs a no4? like what pops out instantly to let you know it a no1? whats it worth?
If the irons are still on it, that can be an easy giveaway. No1mkiiis have the U style notch for the rear sight on the barrel between the reciever and the front sight. No4s have an aperature/circle type on the reciever. Basically see if the rear sight is a notch, or a circle. (that's if it's not one of those sporters which have had non military sights added on)
