Comment 7 for bug 1592747

Filtering based on model_name appeared to be a wild goose chase.

I realise it is a better idea to check if the serialnumber is ready for
decoding:

  AND serial ~* '^[a-z]{3}[a-z,0-9]{8}$'

After testing this report over all our chassis/modules, all production weeks
are now between 0-53 and production weeks have sensible values.
