The Perry plastic mounted-men-at-arms has 4 types of armour.
Now the most recognisable 'extremes' of late 15th century armour styles are
1 - the Italian/Milanese form, with large smooth plates and asymmetrical arms, suited for cavalry combat (the left side being more fortified with little mobility needed, the right side (weapon arm) needing more mobility).
2 - the German/Gothic form, with a slimmer, tight-waisted outline, lots of decorative fluting, and symmetrical arms.
HOWEVER - there are many, many more forms that blur these lines.
There is a fantastic series of books by Dr Tobias Capwell which detail English armour of the period, which he demonstrates was quite distinct, and also (in vol 3) imported European forms of armour that would be seen in England, most notably armour that is basically Italian in form and construction, but adapted to English / West European tastes - basically a little extra decorative fluting, and more flexible for foot combat rather than purely mounted combat.
Ok, so the Perry set has:
1 - Italian
2 - German
3 - English
4 - A body with a tabard / livery coat, the armour which can be seen underneath looking somewhat 'Italianate'.
Having recently read the Capwell books, I have a few thoughts on this Perry set, I might even dare to call them criticisms!
1 - German-style armour was rarely EVER seen in England, in particular the famous late-period gothic form they have used.
2 - The 'English' set they use I think in the notes they also call Flemish, but this is NOT correct - the Flemish form of armour of the period was very different. Their English armour has all the right features (lots of cusping), though interestingly its distinctive pauldron (shoulder) shape is barely touched on in the Capwell book.
So yes, the Perry set will get you two Italian armours - one covered, one uncovered. It will also give you a German armour and a distinctly English armour.
