I can’t remember the name of the place to buy the 1933 in 1934 wind wings, I think it was in Oregon or Washington state, maybe Ron’s auto glass? They supply exact correct size and have the black edges. I do my own rose etching, see photos, I use the very simple and inexpensive Armour Etch, or Rub N’ Etch, that you can get on eBay or any hobby store.
