Okay Gentleman and Ladies, I am looking for a hen's tooth, I need a caseback that will fit a 7004a. A correct Wittnauer case would obviously be the goal, but could there also be another caseback model?

I'm attempting to use Ranft for movements and makers but coming up zero....any shared knowledge is appreciated!

 

242T would work right?

 

Ha! Not sure that would be an appropriate use of parts! Actually I'm an idiot, just realized that these share a case with the Croton/nivada chromomaster
