Where, in an action for a broker's commissions on a sale of real estate, the court charged that the jury should find for defendant, if a specified condition had been imposed for the sale, and the sale was made without reference thereto, an instruction that if the broker by himself, or through his sub-agent, produced a purchaser ready, able and willing to buy on the terms agreed on between the broker and the owner, the owner was liable, was not misleading, for, if the specified condition had been imposed, the charge required proof that the sale had been effected accordingly. Hansen v. Williams (Tex. Civ. App. '08), 113 S. W. 312.
