My just received 1970 (serial E8325) Raleigh Professional ("the white one") frameset has what appears to be "EDA" stamped in an oval on driveside top of the bottom bracket shell. Does anyone know what this stands for? It's a very similar stamping to the more familiar BGF bb.

Also, this and other Professionals has what is referred to as "Latin Line" lugs. Were these a house Raleigh lug or possibly Brampton or Prugnat (which they resemble)?
