Ahoy Francisco,
Yes, I agree that the Revell VIIC is highly detailed.....an excellent model.
Also you probably already know that AFV and Hobby Boss make many
1:350 scale subs in the VII and IX variants.
Mirage has also released new moulding in this scale but I don't know
how they compare, I have yet to buy one.
Also I have come to find out that L'Arsensel and Joffy make excellent figures
in this scale, to populate these subs.
Cheers,
Joe
