Allan, Thanks for the information. yes, i'm new here, navigating my way through, and trying to get all the ducks in a row to do a Victory model. the images came from the web, and while i was more interested in a clear illustration of the eyes & rings for asking my question, you bring up a great point about the blocks as illustrated (Notations in the cad-model go > here) .
I feel sort of silly now, i've mainly been using Goodwin's book for the 1745 Establishment, and totally missed the little table about the eyes/rings.
As for the rope sizing, yes i agree that the run-in/run-out ropes would be approx 1" diameter, meaning the breech rope would be at least 3-4 inches in dia. Thinking in 1/48 scale though, to reduce the diameters for each different size gun could be do-able. is worth investigating at the proper time.
Structurally, i would not think the Breech rope rings would be in knees either, but the run-ins certainly could be.
I included a list of the books i've accumulated here IRT HMS Victory and some modelling-oriented books as well. any additional books you can recommend is greatly appreciated. Thanks!
