$750 would be a good price for a standard 1903 rifle with original barrel in my neck of the woods. I am no expert, but I think you did real well for a Mark I with original parts.
BAR, You are of course right, it should be Pedersen but my phone automatically corrects spelling for words it thinks are incorrect. Pedersen corrects to Petersen (but interestingly not Peterson) unless you manually override it which I forgot to do.
Some casual viewing material for those interested:
