My 452 was made by the late Don Brown in WA. I bought it slightly used from the late Thad Scott in MS.
Killed one ancient speed goat w/it near my home at 90 paces. Belly crawling through the cactus and sage with a drag bag at age (then) 69 is real hunting.
WG&F biology guy said it was the oldest speed goat he had ever seen.
I have now "ruined the rifle" by putting an 6X Unertl small game scope on it that allows me to ring the 400 yard gong almost every shot. Mounts are dovetailed into bbl as it must be slightly offset to clear hammer. I also have the huge Venier tang sight for it. Easy resroration for some future owner.
