Thanks, Guys, yes I feel a bit of an idiot, cos when I went to my Harold Bobrof Atlas, there on map page D12, was the most humungous circle depicting a cluster, just north of NGC 6231 is Collinder 316, and inside that one is vb 205

I measured the coordinates of 205 as 16h 56m and 40.8 deg South. That area of sky is absolutely packed with beauties, I will have another look this weekend.
