If you have a CVS or Walgreens nearby you can pick up single edge blades there. Congrats and enjoy!
Jim, i have never seen the razor blades eitherI like the original blades that came with it. Pretty cool and something I don't recall seeing before.

1930 is when ER first stared making that razor. I don't know what you can find locally, your best bet may be www.connaughtshaving.com
Nice razor!
