Wanted-turret cap for old Weaver K4 scope

[cochlan]

Good morning members,
I'm doing some work on dads old 10-22 and he has an old weaver k4 steel scope and it is missing one of the turret cap. The caps are all steel with a "checkered" pattern for grip on the outside. I would like to find a replacement cap, and if nobody has one kicking around I would be willing to buy a k4 and rob the cap off it. Thanks in advance.
