Hi Allyssa,
I can’t find exact knobs to match either of the two styles that were on those pieces. I think what I’d like to do is buy new knobs that have a retro look.
Here’s a few I found – I can buy them or if you want to purchase and just charge us for them.

These a a little bigger – 1.3″ (closer to the size that was on) and we’d need 2 packs

Or these at 1.5″ dia.

Or change it up altogether … 1.5″ dia
