Used to own that bow back in the 70's, decent shooter but did not like the gap between the top of your hand and the arrow shelf. Good bows made the past twenty years have the arrow shelf right at the top of your hand for good instinctive shooting. Makes a big difference.
Anyhow, to your question I would say go to the Trad Bow Sites and see who the arrow suppliers are now. I believe Rose City is still in business and providing good cedar shafting (my favorite). Three Rivers Archery is a good one to pull up on line, you can get anything you need for arrow making from them.
To be honest with you I would be making a good carbon shaft nowadays as you have to buy a lot of cedar to get a matched dozen nowadays or pay the price for matched dozens. Custom arrow makers are out there and some are superb and you will pay dearly for the quality arrows they make.
Find some good carbon shafting, order them with feathers instead of vanes and they will do fine for you.
If you go to Traditional Shoots these days you will find a large percentage of current shooters do just that.
