Success! I got the lens off, it was so simple I feel like a dunce. The bulb does not work., so that is next. This machine(Audie) has been a lot more difficult than my first one. I did find one just like it on needelbar, but I guess that won't help me much now. It was a singer miss-labeled one so I still don't know if it's a 99-13 or a 99-31 crinkle.
I guess this is part of the fun?
