In November 1999 Stephen prepared this Sunbirds box as a trial just in time for it to be accepted for the second Moorcroft Enamels catalogue of 2000. The trial piece shown here has the anvil (A) year mark but the pieces produced for the edition of 50 would have had the balloon (B) year mark. It is one of the few Moorcroft Enamels pieces that featured non-British bird species.

Moorcroft held back a lot of trial pieces like this, together with number 1 of each edition, but sold them off when the decision was taken to close the company.
