Sekonic L-328 for reflected light

Do any of you know where I might get the Reflected light filter for the Sekonic L-328? I have the Lumisphere but not the attachment for reflected light.

Have you contacted Sekonic?

I just went through the same exercise with a Sekonic L318b meter. Sekonic USA does not have the Lumigrid any more, as of about 4 weeks ago. B&H claimed to have one, but a Minolta part arrived and I had to return it. Finally I bought one from Jack's Camera Shop via Amazon. Better buy soon before all stock disappears.
