Up for auction is a very nice copy of The Pennsylvania Railroad No. 20-D instruction manual for the safe handling of oxygen, acetylene, or other gas cylinders used in welding or cutting.  Also, care in use of gas flame and electric arc when working on locomotives, tenders, and cars empty or loaded.  This booklet measures 4in. by 7in. and contains 30pgs.  One page is missing in the front of the booklet.  Believe this is the form that gets filled out and turned in when training is complete.  Binding is very tight and booklet is very clean.

Shipping for this item will be 3.98 within the U.S.

Let me know if you have any questions or would like more photos.  Thanks!
