OK. I did some digging around for 3 year old conversations and links.
The Grant Technology 306A is the fully-stuffed KWV11 + RTC board. If
it's 1/4 stuffed with just the RTC portion, it's a 307.

One 306A sold last year on fleabay for $27 plus shipping. If I had
seen it, I probably would have bought it.
I don't think there are any photos easily findable online. The manual
on bitsavers has some great technical details but sadly no schematic.
Enjoy,
