Hi Cup_of_Fire,
Welcome to the History section!
The Visconti is amazingly beautiful isn't it? I bought a big set of cards one year and put beautiful clips on them then decorated my Christmas tree with them!
It's wonderful to think that you are looking at images that are over 500 years old! We get to take a bit of a time travel into this other time and imagine what players thought of these images when the tarot was new and just getting popular (for the first time!).
One of the wonderful things about these old cards is that you can read them any way you want. The deck published by LS might have a little white book with instructions, but the original deck probably didn't! You don't have to follow any rules with this at all. You can make up your own intuitive meanings, there are no "right" answers.
This same type of question comes up often when discussing the Marseille Tarots (TdM). There's a recent thread
HERE that might encourage you to explore alternative ways of reading with the Visconti deck. The Visconti deck is even older than the oldest existing TdM, by about 200 years! There's a lot of history in those cards!
Because there is no "right" and "wrong" way to read with these old decks, it's really up to you to decide how you'd like to approach it. You can follow directions in a LWB if that feels good to you. You can transfer other meanings if that sounds like a natural plan. Many people like to abandon those when dealing with antique decks. Because these existed before Waite-Smith and Crowley-Harris decks, they're not really based on them like most of the decks are today. Some people like to use elements and numerology. Others like to use old fashioned meanings from playing cards.
Whatever method works for you is what you should do; but I do encourage you to try leaving all those things you've learned from other decks out of your head and just allow these beautiful images to tell you themselves what they mean.
