Thread: Weaver mount sizes for a Parker Hale SMLE rail

Just got a vintage Kowa scope to throw on my SMLE sporter and it came with a set of Parker hale scope mounts.
However just noticed that the mounts are actually more narrow than what I had with my old scope.
They don't fit the alloy rail I had installed on my rifle which I was told were made by Parker Hale, but don't see any markings stamped onto it.
Was told the scope came off another 303 but must have had a different type of rail installed?
They look nice mounts was hoping to use them, but I guess I need to look for a different rail instead?
See photo for comparison.
