Source for Dahlia sprayers

Does anyone know of a supplier for Dahlia sprayers?  Conservation
Materials used to sell them but they are, of course, out of
business. Their "replacement", Conservator's Emporium, sells the
Dahlia #2 (320 cc) but not the #10 (960 cc) which I am looking for.
Any leads would be appreciated.
