Who makes the fullest range of graded papers?

Been searching around for a couple of hours to scope things out, but I wanted to check you you guys, too:

Does anyone still make a grade 1 or a grade 5 paper? Kentmere makes 2-4, oriental makes 2-4, ilford makes 2&3, but nobody seems to cover the extremes.

I'm not looking to buy any, I just want to send out a product availability feeler or roll-call if you will.

Thanks gang!

Have a look at the offerings by Freestyle, http://www.freestylephoto.biz/, you can search by grade #.
