Speaker stands brand?

They look a bit homemade but a good job at that. You’ve probably already looked at Sound Anchors; if you haven’t, you should.

Yep Sound Anchors cannot be beat but esp for Harbeth you may also see Skylan stands.

Thanks for all replies.
Yes, I've seen Sound Anchors and Skylan stands are most popular for Harbeth speakers. 
The one I showed seems to be made for C7. Size-wise, it fits perfect. 18" height ,and with spikes it can be 19". 
It won't be as heavy as sand filled stands, but it's good to hear that it looks good.
