I suspect its a PH5C as the hole for the forward/upper mounting screw on the charger bridge is not filled.Is it a 5c(#4) or 5d(#8) sight?
No8. Note the previously mentioned mounting hole only found on the No8. The barrel of the Brit. N9 also doesn’t protrude into the action but rather is almost identical to a CNo7.Is that a No.8, a Brit No.7 or a No.9 in .22?
