THE ATTERBURY Motor Car Co., Buffalo, N.Y., are one of the pioneer lorry-manufacturing concerns in the United States, for it is now 21 years since they put their first model an the market. In fact, they claim to be the oldest company in America that has specialized in lorry manufacture. Considerable experience, therefore, is behind the newest Atterbury product, a lorry of 2-ton capacity capable of attaining a speed of 30 miles per hour.
The manufacturers are of the opinion that this medium-capacity speed vehicle will supply a distinct need in the 'United States, as it is capable of carrying a fair-sized load at the maximum limits of speed that the laws of the respective States allow. The opinion is expressed, also, that the Atterbury Highway Express for such it is christened, will make a distinct appeal on this side of the Atlantic, and dealers interested in securing representation for this vehicle are advised to get into corn-munication with the sales department of the company.
We have expressed the opinion before that the day cannot be far distant when regulations will permit of high-speed lorries operating over many of our highways, and chiefly on this account is the new Atterbury product of interest to our readers.
