There is no way to tell what variety it is at this point; it may not even be a "snap bean," the young pods of beans normally used as dry beans are often fine to eat as "snap beans" but become fibrous and stringy pretty quickly. Even once the pods mature and dry it will likely be impossible to say for sure what the variety is.
All we really know is that it is a "common bean" (Phaseolus vulgaris).
@byulasfjazz -- are the plants climbers or bush beans?
