Source for metal stern reqd & pennant issue

1. Does anyone know the source used for the metal stern provided for the Themis (French Navy Fleet set)? The original builder’s model & the picture in the Trafalgar Companion book (Mark Adkin) show it as rounded i.e. more like the middle generic one provided on the plastic sprue.

2. The Spanish (mainmast) pennant is not a mirror image; therefore, one side is always upside-down when folded together.

There are a number of other small errors including missing drill holes for the Stays in the hulls of all 1st Rate models & a seemingly incorrect figurehead for Victory, but these can be easily fixed.
