23 is the long handle. http://www.classicshaving.com/catalo...941/284064.htm
I got mine at QED, but you have to email, as it is not on the main shopping page. I like this one...it's the one I started with. Even with the shorter handles (I picked up a Gillette super speed at an antiques shop), try gripping just the end.
See Kyle's great primer for holding the razor:
[FONT="Trebuchet MS"]I do not belong to the school which holds that aggression is to be met by concession. Mine is the opposite creed, which teaches that encroachments must be met at the beginning, and that those who act on the opposite principle are prepared to become slaves. In this case, in particular, I hold concession or compromise to be fatal.[i]--John C. Calhoun of South Carolina[/i][/font]
