Recently at the OGCA show here in Ohio I saw a book on the Spencer. The dealer told me with some small emotion that the book was no longer in print. He then said that it was going on the web for 200, but that since this was Sunday and his copy had been on the shelf for a while, I could take it home for a paultry 175. Needless to say, I did not get it. Is there anywhere on the web that the different calibers the Spencer was converted to is talked about? I have heard many different tales and would like to know what is truth and what is not. Thanks so much,.....Ramon
