[Pibe-division] Grade Three Braille Reference?

[I. C. Bray]

Hello, All.

I was wondering if anyone out there could direct me to, or otherwise send me 
a usable / readable reference to Grade Three Braille.

I know it is not commonly used, but the work has already been done, and I 
want a copy.

Most people make their own "Short-Hand", but I'd rather use something 
standardized...

Call me quirky!!  LOL!
When I was sighted, I ran
across an online reference list... I am unable to find it now.

Thanks,
