PARTS ENVELOPE
The A. C. Gilbert Co. parts envelopes for sale. Form 1135. These were used by the factory to put various parts orders from them to dealers, for identification purposes. Size of these envelopes is approximately 3" X 5 1/2". I had these reproduced in the 1970's when I was more into the American Flyer "S" parts business, and have a few left over to sell.
