I apologize for the above post. Thought I was replying to a particular post, not to the thread. Oops!
In this thread, post #69, quiltingweb posted a pic of where the serial number could be found on the NLB. I'd been searching for that for AGES!
Now, if only I could find a bobbin and bobbin case for it.
Anyone have a date (or range) for serno: 486435? (I'm fairly sure that third digit is a 6, not an 8, but the plate is pretty scratched up.)
