Can you help me figure out the breed and age please?!

I bought this bunny on impulse a couple weeks ago, then did all the research that clearly advises not to do so. Anyways after a lot of work getting ready for this commitment and educating myself on rabbit care, I'm dying to know what breed I have and possibly how old he is. I know he is not full grown, the seller said he would get about twice the size... I don't know if I would be able to find the seller again to ask.
Help Please
