I think you might be correct to challenge his definitions.....

...come again?

Service blocks were made for several years after actual production units were made...as spare parts. Some say they were not as well cast as the early ones.

With respect to "NOS" blocks...40 years after they were made...
...I know in my business "new-old stock" stays in the warehouse because they were either customer returns or they had problems and just put it back and grabbed another one.

Also remember a part is only NOS until you use it....then it's just a regular old used part.
