And still different, with twin-hull layout (the next ones will have a single hull):

Thanks Ericr!

And with a single hull (and Single Float), thanks Caveman:

THis is the last one I've found in archives (up to now):

Thanks!

An overview in small size appears in my collection below:

[PR19_Kit]

The centre one in the bottom row had to be built with a permanent fin offset, by about 30 degrees!!! 

[Tophe]

I may try, but in which direction? (1/ front of the fin to the right/towards us or else 2/ to the left/far from us?).
Well I try to think a little by myself: the propeller on the left, with drawings, about the tractor effect made rotation and airflow on an oblique fin also rotation (in the same way increasing imbalance or else: opposite for balance), I guess my second hypothesis is the right one, yes?

[PR19_Kit]

With the engine way out on the port side, the aeroplane will naturally try to turn to starboard the whole time, so the fins need to counteract that by producing a port turning moment.

This would need to leading edge of the fin to be turned to starboard, like this.

[Tophe]

Thanks, this is matching my own conclusion (final):

I will draw the corrected P-38S soon.

Here are 2 versions with big engine asymmetry compensated by oblique fins, and one version asymmetric while the engine is symmetric:

Oo, I like that one on the right.

The one you like had derivatives with 2 and 3 engines of course (like the Savoia 55/66/77):
