10 - Just like the day it left the factory. Not a scratch or mark upon it. [Only two machines have been seen in this category.]

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.
