What Does A Parker's No P G 4 Sight And Muzzle Protector Fit??

[albayo]

I have come into my possession a Parker's No P G 4 sight protector and it doesn't fit any of my guns.
Does anyone out there have any idea what it fits?
I may also be in the wrong forum, and my messages are full and I haven't figured out how to clear them.
Thanks
Al

I think it's a standard Parker hale front sight hood isn't it? .303s they sporterized?
