Betsy,
As an avid grower and one-time (novice) hybridizer of brugs, I can tell you that there are so many pink brugs that look exactly alike, you will never be able to positively ID your particular brug, short of genetic testing. You could probably "positively" ID this one as a dozen (or more) different cultivars.
It looks like a nice one, and if you love it, then just enjoy it as your "no name" pink brug. Unless you can either find the tag or possibly remember details of when you obtained it (and possibly refer back to whomever you received it from), it's best that you don't try to pin a name on it. If you decide to trade it, then just do so as a no name pink.
I have several pinks myself that are beautiful, but after several moves and an ongoing war with the squirrels in my neighborhood (who seem to have an unnatural affinity towards plant labels
) I've lost the tags on them. I've had to resist the urge to ID them for the very reason I stated above. But, I love them anyway and continue to grow them in my garden because they're good performers and are such a sight in full bloom.
