I scored a Singer 99 in a pristine cabinet tonight - absolutely thrilled with it!
No bobbins (but I already have some) and I found a Singer 'automatic needle threader' in the original packaging in the box of attachments - what a bonus! 99's are fairly common in my area - but finding them in a cabinet is very rare.
PS This is either my 3rd or 4th model 99 - the others are all in portable cases. This newest score is destined as a Christmas gift to a step-grand-daughter.
