The video from the Featherweight shop only addresses cleaning the outside (works great too) From what I've read about the smell inside the cases it is from using the type of glue that was available at the time. That being the reason the only way I can see to eliminate the smell is to remove the lining clean out the old glue and reline the case. I did read that some people had success using heat to remove the odor but that doesn't help with the poor condition of the interior fabric. I can't figure out why the case is so damaged on the inside but the machine is nearly pristine. Other than a few surface scratches it looks great, even the decals aren't marked. Maybe they left the machine out and used the case for something else...
