Background:
In 1939, my Granddad purchased a new Colt .45 Government Model M1911A1. He was a bullseye shooter, and made a mod to the sights for a better sight picture (nice wide front blade, wider notch in the rear sight). He also replaced the curved backstrap with a straight version; but kept the curved backstrap.
When Granddad passed away in 1980, I wasn't able to convince my Dad that I needed it more than he did.
One day while he was shooting it, the original walnut stock split clean in two on one side with the grain, right through the screw holes. Naturally, I chastised Dad for trashing it (half in jest, of course).
A few years ago, I was visiting my folks - and Dad decided to attempt to repair the crack, using Gorilla Glue. I have no idea what possessed him to use that stuff.
Dad took his final flight a year ago, and I took possession of this fine old Colt last summer.
The Gorilla Glue left a visible nasty yellow seam running right through the stock.
I have considered trying to chip it away using a checkering tool or perhaps a scribe, but I realize that my skills are rather limited in this area.
Does anyone have suggestions as how to minimize this ugly yellow joint without damaging the original checkering or finish of the rest of the stock?

Grandad's .45 is the blued Colt. The cracked stock is the left one; not shown.
The other is a 1917 Colt M1911.
