Well I didn't expect any replies so thanks for that. I wonder if the drummer you refer to was either Avreeayl Ra or Ernie Adams? I have since found a conrad kit for sale (sold) and the photos looked like a cheap beginners kit so they obviously make a range. The one that I have seen for sale looks like an intermediate - a bit like a
sonor force 3007 for example although I think the conrad actually looks better in terms of quality, finish and hardware though.
None of them are badged and the only thing that can be seen is the conrad (in capitols) on the front BD skin.
