The primary value of the company are in:
1. the quality of its products
2. the network of artists, producers and dealer network
3. The customer base (declining significantly since the peak, but loyal)
To my list I should have added:
4. Harry Hine & Tony Constantino (probably ranked higher than #4)
and to #2, I should have included the archival and continuing work of Paul Brady on behalf of the company.
