Blue Filter in B&W Photography Question

I realize that blue filters are rarely used in B&W photography, but I'm surprised that it's so difficult to see sample photos using this filter on the Internet. It seems that even people who buy them don't post reviews with photos.

If you have a photo or photos illustrating the effect of a blue filter, I would like to see it. Comments on what effect the filter produced would also be appreciated.

Genuine blue filters have a guide number of #47 and this is what I'm referring to.

I don't know how the #80 Blue filter is different from the #47.

Thanks!
