Mail Vans Mr. DAY asked the Postmaster-General whether there are any motor mail-vans at present in the use of the Post Office of which the chassis are of American or foreign manufacture; and wilt he give particulars. Mr. LEES-SMITH The Post Office has in use four mail vans with motor chassis of wholly American manufacture. These were obtained in 1928 for experimental purposes. There are also 799 vans of which the chassis contains a small percentage of parts of American manufacture. The remainder (1,584) are of wholly British manufacture.
