Ryan, when you see an SGN112 Spanish 74, then SGN104 should have been just slightly larger than that. (SGN112 is better for Bahama and the later Ildefonsos than the Nepomuceno group, which were around Temeraire size.)

I'll see if I still have your email and if I do I'll send you a PDF with the four major variations of the 1744 Invincible family-tree. (Two sets of drawings, 1/500 for more detail examination, 1/1000 for comparison to game miniatures.) If you've downloaded my Line Chart document that I just corrected and re-uploaded, all the drawings in that are 1/1000.
