William,
I have a couple of : 1817-19-38%'s and 1819-19-38%'s still in stock.
We are reducing the diameter a little on the 1800 series with great results.
If you are going to run them full bladed you better have a ski on the tub unless
you reduce the cup on the trailing edge.
Let Me Know If You Still Need Them?
