The quill spring is heavier than tape measures, seatbelts,clocks etc. From what I can see on google images your DP is fairly common and the spring is readily available as a spare part from ebay, and probably local tool repair shops as well.
If it is only one end broken off you could anneal the tip and fold it to the desired shape. If it is just weak to retract the quill it could need cleaning and adjustment.
