Alex do a search useing springfield 1903.com
You should find the site for collectors of 1903's.If your gun is low number original it should be in the 1000 plus range.I saw one advertized on a site for 2500 but I think it was out of line.I think I would do my business at a different shop.If they try to rip you once they will again
I have a 1903A3 close to original and I turned down 500 on that one.I know yours is worth a lot more then mine.
