Thank you!
For the tail I more or less invented the area with the scales in circumflex accents, we distinguish them perhaps or vaguely in the photos.
Ditto for the webbed leg at the back. Not sure it's there or even there is one.
There remains the tooth to redo with white paint, white spots of the crest, the tongue, etc. etc.
The guy who painted this crocodile in 1916 was drawing very well. The scales and the different plates follow very well the shape of the body and their rounded shapes give a volume to the body. It is effective and very successful I think (we must look at the original ... of course).
Regards.
