A Glen Ellyn, Ill., company has launched the latest in a series of fund-raising cooperatives that will result in the awarding of scholarships for which Utah postal employees can apply for their families.

The Yorkshire Co., a firm that makes die-cast detailed authentic replicas, is selling miniature replicas of the original 1929 Model A Ford postal delivery trucks with the proceeds going to awarding of scholarships, according to Hy Kahn, Yorkshire vice president.Kahn said the company already has awarded 25 scholarships to relatives of postal employees this year, and by the end of 1990 that total should be 100. They can be used for either university or trade school educations and are awarded by a panel based upon accomplishments of the applicants.

He said each 1/25 scale truck has a serial number and is 61/2 inches by 31/2 inches and contains such details as spoked wheels with side-mounted spare, driver's compartment with seat, steering wheel and column, dual rear-view mirror, sliding doors, stick shift and parking brake.

The exterior is painted with the original color scheme and is highlighted by Uncle Sam "I want you," posters, windshield wiper, chrome-plated front bumper, taillights and a chain and padlock to secure the rear doors.

The trucks are available by mailing a check or money order for $29.95 plus $3.50 for shipping and handling to E.C. Hallbeck Memorial Scholarship Fund, Department 300, 1300 L St. Northwest, Washington, D.C., 20005. Allow four to six weeks for delivery.

Kahn said there will be other releases of collector's items covering the history of the U.S. Postal Service.
