I have a 1892 Winchester that was in a house that caught fire, there was no damage to the wood but the action is frozen. This occurred 20 something years ago when I was a kid. The other guns function fine, only the action if frozen on the Winchester. I have tried applying WD-40 and other oils to loosen the action, but to no avail. There rifle is relatively rust free. The gun was partially disassembled by my Grandfather, who did not have any luck and then sat in a box for 20 years. I have a take down guide and have not been able to finish disassembling the gun. Any help would be appreciated.
