Hi Dick.
The reticulation on an Asagi defeats most pin designers and manufacturers.
However, there are a few notable exceptions.
1. The 2002 Central California Koi Society show pin.
2. As Andrew said, the 2004 South East UK pin.
The BKKS tried to make one for its 1997 show pin, but it wasn't good enough so we resorted to the Shusui. But there were 4 Asagi pins made. You can see it on
www.koipin.com
Because of the complexity most clubs resorted to depicting the Shusui when making a pin to represnet Asagi/Shusui class.
But nowadays the pin manufacturing processes are more advanced and there are methods available that can convey this amount of small detail, so hopefully this situation will not continue.
