I suggest writing a letter inquiring about the missing information. About 25 years ago I purchased a new switch from a well known hobby shop. When I opened the box it was missing the instructions and warranty card. I wrote a letter to Lionel asking that it be put into their warranty list. To my surprise, 2 or 3 weeks later I received a box containing an apology letter, a warranty card and a brand new box car, worth $25 at the time. This also happened to me with another item not related to trains. I believe in the power of the pen.
