Red Emulous bulls

Can anyone tell me about these Red Angus bulls?
Red Emulous 69D and Red High Price.
I know there was another, Biffles Emulus, "Big M" that was a red carrier.

There will be more than 3 that were red or red carriers.  Dynamo might have been the main one.  Patriot, was a dynamo out of an emulation 31 daughter,  there were a lot of those scattered through the country,  the black breeders shunned them, the red breeders were just as scared,  too much gas in the tank, disposition could be not so good,  made great cows though. Have a red dynamo son in the tank,  haven't used him in years but did have a few cows.  There is semen in the deep dark corners of the studs,  just have to dig.

Interested in seeing any cattle alive to these bulls. Have a few projects up my sleeve.
