A friend's 1953 Featherweight has a broken gib hook. Luckily the screw is still there. I think the best way to fix it is to find a bobbin assembly, take the whole thing out via the set screw and replace. My skills probably aren't up to replacing just the gib hook.
Anyone got a source for parts? So far I'm seeing 'out of stock', no longer available', and 'are you kidding'?
