While it is true that you normally ALWAYS remove the fore end before tightening or removing the butt stock screw, the fact that you have an 1949 Ishapore MIGHT be the exception.
Ishapore did away with that problem in the 1930's (if my memory is right) and introduce the back reinforcing strap instead of the bolt stock keeper plate.
IF you have that ''strap'' at the back of your fore end it means you also have the shorter butt stock bolt.

Ishapore is well known for recycling and reusing their older stocks so i would strongly suggest you post a picture of your rifle with the same area i just showed you and have guys visually confirm this to you before you attempt anything.Information
