I don't know specifically, but I've seen (and even practiced - early 80s) a few old RAF procedures from that era that used the teardrop turn to final approach track. Specifically they were NDB or QGH approaches with the fix on the field.
I think you approached on reciprocal +/-20 or 30 degrees, flew 1-2 minutes outbound then rate 1 to intercept the FAT while descending to platform height.
I can't recall rules of thumb for crosswinds. You are already established on drift-corrected heading as you transit overhead, so need to adjust for about 1 minute drift on the inbound turn; much as a teardrop entry to a hold.
The QGH could be a bit of a radio hog!
