Old-style tang sight for Marlin Model 39 source?

[MD]

I've got an old Marlin Model Model 39 .22 that someone drilled holes in the tang for a tang sight.

Where would I start looking for one of those sights please?

some of those are factory holes for tang sights, old ones, Take lots of money when you go shopping for tang sights.
I did have the ordinal factory one , but sold it.
They make plug screws to fill the hole when you don't have the sight.

Pro-line sports in cowtown may have what you need, they are "Marbles" distributors and keep a fair selection on hand.
