I well remember the Pam 24, 25, 64, 87... I must admit I lost track after the Pam 199, which was also an interesting Submersible in the Regatta line.
I also remember the Pam 243, which was a nice 47 mm Submersible, and, of course, the Pam 341, monstruous in size, beautifully designed, though...
And the first Destro Submersible, launched for a parisian AD, some long years ago.
A rich family, indeed!
Best, and thanks for this interesting post.
