General: Early 70s British Falcon

I've come across an early 70s British Falcon frame which has been stripped of everything but the BB and headset/stem and was once repainted. It doesn't have any chrome on it or the fork. The only identification is the one seattube sticker that remains similar to 8836 here on Velospace. The headbadge is beatiful and still in place also. I've done some extensive research and it looks as though it may be a "Supporter" model because of the yellow paint under the downtube sticker and the two frame pump pegs on the downtube (it has no other braze-ons. I've ruled out the San Remo and a few other models, the Black Diamond is close, but I would like to find out if anyone has any knowledge of old Falcons?
