I recently purchased this Luger #4824u and realised the trigger and ejector are not blued or colored .....the trigger has been blued along the very top....it does not appear to have been sanded,polished or otherwise played with.....but obviously this is not a normal finish.....also all the parts match on the gun except the firing pin which is #14.....I handle quite a few Lugers and this is the 3rd Mauser Luger(in the last month) from the 1939-42 production era that has one small mismatched part where the last digit

is correct...but not the first digit....in each case the gun is original and in my opinion had not been played with.....has anyone else encountered this mismatch scenario???...Thanks....Peter...
