Did you check out the OEGBCA site? They have over 100 photos of good BBRs. Go here:

Years ago when I bred Black OEGBs, I also had a couple pairs of BBRs and saved this info. Don't know if this is current, and can't offer attribution, but it should be of some help, along with the photos at the OEGBCA site. When you get serious about exhibiting, then buy the standard listed at the top of this forum section.
