The plaintiff, G. V. Halliday, is engaged *287in the manufacture and sale of safes under the name of G. Y. Halliday & Company. His manufactory is located in Cincinnatti, Ohio. He has a place of business in the city of St. Louis for the sale of manufactured stock. The defendant executed and delivered to plaintiff the following order.
“Mexico, Mo., 11 — 1, 1898.
“Please ship as directed as soon as possible one No. 10 Excelsior Eire-Proof Safe with inside doors as illustrated in catalogue on page 10 of the dimensions and plan of interior as specified on the back of this order, marked to W.

“W. H. Lesh.”
The plaintiff alleged an offer to comply with the contract and a refusal on the part of the defendant to receive the safe. The answer is a general denial. At the close of the evidence the circuit court peremptorily directed the jury to return a verdict for the defendant. The plaintiff has appealed.
We are not advised of the views of the learned circuit judge, as the respondent has not favored us with briefs.
The contract is unambiguous, and unquestioably it is an unconditional contract to purchase a safe of the description mentioned. The stipulation that the safe was not to be shipped until the plaintiff received a specific order from defendant did not make the purchase conditional. Under the contract the defendant was bound to order the shipment within a reasonable time, and having failed to do so it was the plaintiff’s right to offer to deliver the property. Having done so and the defendant having refused to accept it, the latter became liable for damages for the breach of the contract. Touching the proper interpretation of the contract it could make no difference, that at the time the order was received, the plaintiff’s manager was of the opinion that it was not in its legal effect an order, as the evidence introduced by the defendant tended to show. That evidence was incompetent and should have been excluded.. The contract is unambiguous. It is only where there is an ambiguity in a writing that the interpretation placed on it by the parties is admissible. Deutmann v. Kilpatrick, 46 Mo. App. 624; Moser v. Lower, 48 Mo. App. 85. There was not a particle of evidence tending to prove a nonacceptance of the order by plaintiff, but on the contrary he immediately upon its receipt advised the defendant of its acceptance and subsequently offered to deliver the safe. We are therefore at a loss to know upon what ground the *289circuit court based its instruction. It is true that tbe plaintiff failed to introduce or offer any competent evidence of substantial damages, but he was certainly entitled to recover nominal damages, as the making of the contract and its subsequent breach by the defendant were not denied. We therefore conclude that the circuit court committed error in directing a verdict for the defendant.
As the cause will be remanded it is proper for us to indicate our views on other questions which are presented in the record and which must arise on a retrial.
As damages the plaintiff offered to prove (1) the profit he would have realized had the sale been consummated, i. e., the difference, between the contract price and the cost of production; (2) the expenses of its salesman during his stay at Mexico, and (3) additional cost for extra printing and decoration. The court rightly rejected this testimony. It is clear that the plaintiff misconceived the rule for the ad-measurement of damages in such cases. As the safe was not made to order, and was of the dimensions and quality of safes of that number and description manufactured by plaintiff for the general trade, it must be treated as ordinary merchandise, and the measure of plaintiff’s damages for the violation of the contract is the difference (if any) between the contract price of the safe and its market value at the city of Mexico, the place of delivery. To this difference may be added any reasonable expense incurred by plaintiff in attempting to comply with the contract and any additional cost for extra ornamentation of the article so as to meet the requirements of the contract. Black River Lumber Company v. Warner, 93 Mo. 374; Northrup v. Cook, 39 Mo. 208; Rickey v. Tenbroek, 63 Mo. 563; Kingsland v. Iron Company, 29 Mo. App. 526; 2 Sutherland on Damages, sec. 647. If there is no established market for the article at Mexico, its value at the nearest and *290most convenient market, less tbe freight, will be the market; value. Anderson v. Frank, 45 Mo. App. 482.
The circuit court permitted the plaintiff’s salesman to testify that at the time the order was given the plaintiff had a safe in St. Louis answering the description of that mentioned in the order, and that that safe was the one intended to be sold. This evidence was competent. It did not vary or contradict the writing, but was admisible for the purpose of identifying the subject-matter of the contract. Skinker v. Haagsma, 99 Mo. 208; Welsh v. Edmisson, 46 Mo. App. 282; Long v. Long, 44 Mo. App. 141.
For the error pointed out the judgment of the circuit court will be reversed and the cause remanded.
All concur.
