i'll bite. WW how did you do it in short?
woofer
VERY careful use of a saw, drill, dowel pins and epoxy on the forend tip.
A fit up and install of a checkered metal grip cap to replace the elcheapo plastic one that was also very carefully sawn off...
IIRC, I used a brand new dovetail saw.
Then a very simple finish strip and re-oil as well as install a non white line Pachmayr Competitor,on my first attempt at it a few moons ago..........
"Before" photo...
"After"...the white lines disappeared and the metal turned Plumb Brown...
"Latest Version" newly oiled, newly barreled/chambered and Fit-4-Dutied.......
