I found this while wandering the Internet, it originally came from the ISMACS website. Unfortunately there are no 10s in my herd/hoard.
Condition Chart created for the International Sewing Machine Collectors’ Society over 20 years ago. It was quickly picked up by enthusiasts all over the world and is now the universally accepted way of describing a machine.
10. Just like the day it left the factory. Not a scratch or mark upon it.
9. As 10 but with the small, odd scratch or wear mark evident to very close inspection.
8. Very good used condition. All paint good; all metalwork bright. What the average antique dealer would call “perfect”.
7. Good condition but rubbing of paint evident and/or some nickel plating worn.
6. As in 7 but more wear to paint and/or some light surface rust to the bright work.
5. The average, hard-used, ill-cared-for machine looking for someone to love it.
4. Poor condition, chipped enamel, rusty metalwork but acceptable for a collection if a rare machine.
3. In need of restoration but a reasonable job for a dedicated enthusiast.
2. Total restoration needed to paintwork and bright metal. It's a brave collector that takes it on.
1. Spare parts only and these would be in need of extensive restoration.
