Fun! I think your best bet is to get some samples of a few different styles to see if you can piece something together and make sure the finishes match. Baldwin has some knobs and pulls similar to the ones you posted:

I'd just get a few different ones from different brands to see if they work together.

I found that Look In the Attic <https://www.lookintheattic.com/?gclid=CjwKCAjw7MzkBRAGEiwAkOXexK37ovoruh7KV7eWgsxMYr4cPZ6IV8KkPkZEi8TLi7QNDYwALffZsBoCgUUQAvD_BwE>; has an amazing collection of hardware and the prices are excellent. They were very easy to work with when I was selecting pulls for my new kitchen cabinets.

I should have added my mom is in the industry so we have access to a lot of vendors but that knob I haven’t seen mimicked anywhere. All of the similar ones have the top rope which look identical to the ones sold at Home Depot by Amerock. I found these by Hickory. The pull is pretty close, a little more chunky masculine but the knob, ugh. Is it that awful?
