Hi Gary,
... "famous Piero"... too much for me my friend!
Yes, the japanse converison cam from "North Wing Model Craft". As maybe you already knows, this converison set is designed to be used with the old Tamiya Harrier/Sea Harrier kit. The resin details of this conversion set are very good, especially when you compare with Heritage set. Panel lines are correct, sharp and clean.
I decided to use the tail section from Heritage because look better in the general shape and size, compared to the same piece from the japanese company has a strange "coke bottle neck" effect in the middle. I didn't found any picture of line drawing that prove that.
I'll put the vertical tail from the japanese company because is very well shaped and with fill details.
Also, I used resin jet intakes from Pavla, so is very strange that this mixture of different resin set designed for different kits just has a very good fit to a kit not designed for...!
As refernces I used pictures from various sources and 3-views drawing from old model magazine and form FAOW Harrier book.
I hope this can help you and I'll post other pictures in the next days.
CIAO!
Piero
