Reid owned a car and travel trailer that he wished to sell. The trailer was outfitted with a stove and refrigerator as built-in equipment. Reid had added a small plasma television set as a part of the equipment, but the television set was not built into thee trailer. Calder expressed an interest in the car and trailer, and also examined the equipment. Reid advised Calder that the price was $21,000 and that the television set would be $1000 extra if Calder wished to buy it as well. Calder indicated that he wished to do so. Reid prepared a written purchase agreement that itemized the car and trailer, but simply referred the appliances as "equipment". The contract price was $21,000, and the agreement called for a deposit of $1,000. Both parties signed the agreements, and Calder gave Reid a deposit cheque in the amount of $2,000. Reid changed his mind about the sale of the television set. Shortly before Calder was due to return for the car and trailer, Reid telephoned to say that he was selling only what was specified in the written agreement. Explain Calder's rights (if any) in this case.
