Shen Hao Cameras, Opemus Lens Board

I have two Questions

1. Some time ago I saw the Shen Hao cameras listed on your site or was it JandC.

Now they are gone, what happened ?

2. You carry lensboards for Opemus enlargers. Are the reccesed 39mm thread lensboard for Opemus 5 different from the lensboard for Opemus 6 ?

Thanks in advance
