Not being a Tiger connoisseur I can only offer some advice I’ve seen here. We have a campaign going at the moment which may have posts of relevance to your questions. It is Put a Tiger in Your Tank! - Tiger Build Thread
Also David Byrden has a lot of knowledge and experience with Tiger tanks. I believe he is often consulted by modelling companies regarding their planned Tiger releases, although unfortunately they don’t always listen to him! His site is https://tiger1.info/
