| | Subparts for Black Falcon and Wolfpack Patterns ?

When I fix the bowties in the Black Falcon and Wolfpack shields (this weekend), would it be more sensible to make each pattern a subpart (or two), which could be shared between shields, torsos and flags, scaled appropriately? If I had done this to (...) (25 years ago, 7-Apr-00, to lugnet.cad.dev)
