Welcome, Linda.
I'm not sure which chart that was referred to that is no longer available. There are several on this board that are more knowledgeable and may be better able to help. If you have specific ones that need to be identified, I would suggest posting pictures and possibly with dimensions.
In the mean time, I would suggest possibly checking out a few links that I have found helpful in the past. Some are specific to Boye and some have images to help identify rather than just numbers.

We like pictures -- hint, hint.
