Mazzie: the 1907 is worth twice the price of the 1903. The 1907 has the 54 and the 1903 has the 64 action. I have a 1907 that I bought early last summer. I got it particularly because I thought it would match ans 2002 air rifle well and it does. I will also have a 1903 soon from parts. I have an older 64 and I recently found a new in box 1903 stock. I also have the current model 1903 trigger on order. The 1903 is really intended as a youth target rifle and that is what I intend to use it for. My daughter is shooting a fwb p70jr and I want a smallbore rifle that will be similar.
