Many of the crosses with jersey will have a reddish tint to their color. The white switch is pretty common with most holstein crosses. I have had several hol/jer crosses that are black and white but with more irregular "spotted" type white rather than the larger white areas of a holstein. But then, have a few that are out of mostly black holsteins, that have little white, more a brownish black coloring. Most all swiss crosses that I have dealt with, and had 2 farms that raised both hol and swiss, and had quite a few crosses; they were mostly a brownish tint black, mostly had black switches on their tail, some had the lighter circle around the muzzle. Once more mature would tend to hold their weight better than a hol x jersey. That hereford cross will beef up nice and doesn't look like they will milk too much although she has a nicer udder than I would have suspected if they were that thin.
I think you got an exceptional deal, under the circumstances. Unless you lose the rest, you will make some money, have a start on some decent crossed beef animals. They won't be perfect, and the dairy will come out for several generations, but many of us have gotten started with animals like this. If one or two are good and friendly, then you can also milk some for the house.
One thing to think about is if you keep heifers and mix them in with the dairy cows, you may run into some problems with the ones with horns. They seem to get a little aggressive with horns after the non-horned ones. Some never do. But most of mine that have had horns, will start to get after other non-horned cows, and they don't seem to get that way until they are 2-3 years old. They can be dehorned, by a vet, but if you do it, wait until fall/winter so flies are one less thing to deal with.
Congrats on making a smart deal and a good start.
