"T"... here are the pics of the laces on the lever... I'll also include a couple pics of the sights... the front is on a dove tail, that is wider than the sight base ( yet ), so it can be drifted into position, then ground down to conform to the base...
the laces are attached to a leather wrap, that looks similar to a pony tail hair do dad...
& this is how it came from the factory...
