Hi Bill!

http://www.spacemodeling.org/jimz/kb-17.htm
Scroll down to the bottom for the fin templates.
There isn't a 1" reference, but I believe the balsa would be 3" wide.

Hope this helps out -

Here is a scan of the full fin sheet with ruler from a Centuri kit. These are the earlier version of the fins with a 'flat' tip on the trailing tip of the fin. This was changed to a 'rounded' tip around '72 or so.
