The CWP T19 from Michael Young is better than the Clark T19. I found that the Clark's crystal distorted the rehaut of the Cartel case making it look wider. The Cartel case is a copy of the MBW, so the proportions could be the same with the same detrimental effect. Here's the link to my crystal odyssey:

Sure Here you go:
Cartel midcase & back
Phong bezel
Gen service insert
Yuki pearl
Singer reprinted dial
Yuki hands
ETA 2846 movement
DWO from Polexpete
Ofrei crystal PA 462-67A, similar to the gen T39 service crystal that doesn't have the curvature of the original T39 crystal
Thanks. Got lucky on eBay a couple of years ago. It's a Singer reprint. Unfortunately I have no idea who remanufactured it, neither did seller at the time.
