If anybody knows of other PDF or documents for other automatics let me know such as 10CRACD because I have that one :-) I'm pretty sure www.mybulova.com will host the PDFs if not I will just as long as I'm not breaking copyright law.

Hi Steve, the holders can be hard to find by themselves. Each case of this movement era has a number stamped/etched inside the caseback, which when referenced against the case parts book should tell us what the movement holder part number is. There is not one holder that fits all cases using the 11ANACB. I don't often see too many holders for sale, so it may be ideal to find a donor watch with the same case.
Provide me the case number, and I can check for a part number.
