Why didn't you post those Guppies? I was planning to do a Italian Guppy IB to surprise you.
I posted not yet any Italian submarine because I am working on the borderline of SB rules: I am using a little more complex template with the standard profile, an "empty" profile and a black waterline silouette.
The idea is to use the black siloutte for the index, the empty profile for the classes and the standard profile for each units.
Anyhow all drawings should be consistent each other mainly depending from period and details level: now I will proceed with this fine tuning for the post-ww2 units.
As an example here is the Calvi (ex Bario - Tritone class 2° series)
the standard SB drawings will come soon
